Version 0.7.0 (2020-02-08)

• New version (minor) including bug fixes, new functions, and function improvements.

Version 0.6.6.9010 (2020-02-08)

• Improvements:
  • Reviews and improves documentation.
• Deprecated functions: coordenadas(), cdfTable(), cdfStats() and cdfPlot(). These functions were developed to fulfill the demands created by the PhD research project (2012-2016) and are no longer (or rarely) used. Some will be replaced, but all will move to a package currently under developed at https://github.com/samuel-rosa/ASRtools.

Version 0.6.6.9009 (2020-02-03)

• Improvements:
  • Reviews and improves documentation.
• Fixes:
  • Deals with the fact that matrix objects now also inherit from class “array”.
  • Deals with the fact that the suggested package geoR has been orphaned on 2020-01-12. This is done by keeping the package in Suggests and using it conditionally by employing requireNamespace().

Version 0.6.6.9008 (2019-01-31)

• Improvements:
  • plotCor: reverses default color ramp so that positive and negative correlations are depicted using red and blue colors, respectively.

Version 0.6.6.9007 (2019-01-22)

• Improvements:
  • plotHD: adds grid lines to histogram.
  • plotESDA: choose the position of the legend of the bubble plot

Version 0.6.6.9006 (2019-01-21)

• Improvements on plotCor to deal with long column names in the correlation matrix. Long column names (> 5 characters) are now replaced with x1, x2, …, xn, where n is the number of columns in the correlation matrix. A message is issues identifying columns and their respective index.

Version 0.6.6.9005 (2019-01-15)

• Adds plotCor, a function to create correlation plots using a colorblind-friendly palette.

Version 0.6.6.9002 (2018-02-23)

• Evaluates the upcoming new version (3.0-0) of the car package.

Version 0.6.6.9001 (2015-12-21)

• Improved selection of the location to place the legend in plotHD.

Version 0.6.6.9000 (2015-12-10)

• A new guess of p_sill is used when the variance is spatially uncorrelated. It is defined as 1e-3 times the guess of nugget (before the p_sill was set to 1e-12, which caused errors in optim and nlminb).

Version 0.6.6 (2015-12-03)

• FIX: corrected error in vgmICP caused by the recent update of package georob.
• vgmICP: Improved estimation of the scale parameter (range) for monotonous variograms by using function practicalRange from package geoR.

Version 0.6-5.9001 (2015-12-02)

• vgmICP: Improve the guess of the partial sill for a pure nugget effect model.

Version 0.6-5.9000 (2015-12-01)

• FIX: the definition of the lag-distance classes passed to georob::sample.variogram in vgmLags was incorrect due to an error in the documentation the former. Instead of “a numeric vector with the upper bounds of a set of contiguous bins”, the argument lag.dist.def of georob::sample.variogram requires “a numeric vector with the lower and upper bounds of a set of contiguous bins”. The author and maintainer of the georob-package has been warned about this documentation error.
• Improve guess of nugget variance by giving larger weight to the first lag because we now consider a minimum number of point-pairs per lag-distance class.

Version 0.6-5 (2015-11-30)

• FIX: the computation of the number of point-pairs per lag-distance class in vgmLags was incorrect because it neglected the fact that, in a full distance matrix, two points a and b form two pairs, i.e. ab and ba. The mistake is due to the fact that we use SpatialTools::dist1 to compute the distance matrix instead of stats::dist.

Version 0.6-4 (2015-11-28)

• New functions have been added. They are designed for three purposes:
  • Variogram estimation and analysis
  • Evaluation of geostatistical models of uncertainty
  • Calibrating random forest models

Version 0.6-3.9003 (2015-11-28)

• New function vgmICP to guess the initial covariance parameters when fitting a variogram model.
• Included description of funding agencies in package description.

Version 0.6-3.9002 (2015-11-27)

• Improved documentation of the vgmLags-function, and added functionality to count the number of points or point-pairs per lag-distance class so that the user can decide if the returned lag-distance classes meet his/her needs.
• New function vgmSCV to compute the proportion of the variance that is spatially correlated.
• Minor improvement of the documentation of almost all functions.

Version 0.6-3.9001 (2015-11-05)

• Developed a new function checkGMU which can be used to check the quality of a geostatistical model on uncertainty.

Version 0.6-3.9000 (2015-09-25)

• New functions:
  • Iteratively de-bias random forest regression.

Version 0.6-3 (2015-07-28)

• Packaging:
  • Now using Travis-CI to check the package after every commit;
  • Functions from default packages other than base are now imported to comply with the new change to the CRAN policy described at http://developer.r-project.org/blosxom.cgi/R-devel/NEWS/2015/06/29#n2015-06-29;
  • Most packages that used to be under the Imports: field in the DESCRIPTION file now are under the Suggests: field;
• Existing functions:
  • cramer(): NAs are now removed when computing the chi-squared statistic;
  • plotHD(): if the Box-Cox transformation is required, the data is now first checked for zeros and negative values. If zeros and negative values are present, the data is transformed into a positive-valued data, with the minimum value equal to 1.
  • plotESDA(): new argument to define the lag-distance classes;
• New functions:
  • Evaluation of the data type contained in an object;
  • Extract spatial trend data from an object of class likfit (see the geoR package for more info): trend.terms() and trend.matrix();
  • Stratification and categorization of continuous data: breakPoints() and stratify();
  • Computation of lag-distance classes for variogram estimation: vgmLags().

Version 0.6-2 (2015-06-01)

• cramer(): the cross-tabulation is now computed using table() instead of bigtabulate() to avoid dependency problems in Windows.
