This document describes how to add new information to the nuclearWeaponStates dataset in the Ecdat package.
The first step is to update the companion “nuclearWeaponStates.Rd” help file.
Then update the nuclearWeaponStates
object so it matches the revised description.
One way to do this is to export the nuclearWeaponStates dataset as a csv file so you can edit it in a spreadsheet:
library(Ecdat)
availInPkg <- objects(2,
pattern='nuclearWeaponStates')
canWrite <- FALSE
if('nuclearWeaponStates' %in% availInPkg){
data(nuclearWeaponStates)
canWr <- try(write.csv(nuclearWeaponStates,
'nuclearWeaponStates.csv',
row.names=FALSE))
if(!inherits(canWr, 'try-error')){
canWrite <- TRUE
}
}
getwd()

If desired, edit the csv file just created as mentioned above. Ignore firstTestYr
and yearsSinceLastFirstTest
, because we compute them in this vignette from firstTest
. That’s because we want (a) firstTestYr
to be firstTest
as numeric years rather than as days since 1970-01-01, and (b) yearsSinceLastFirstTest
to be diff(firstTestYr)
.
If you edit it externally, put it in the current working directory and read it as follows:
library(Ecfun)
if(canWrite){
nWS <- read.csv(
'nuclearWeaponStates.csv',
stringsAsFactors = FALSE)
nWSdf <-
asNumericDF(nWS,
ignore=1:2, Dates=3)
}
(The “ignore” argument in asNumericDF
forces that function to retain the data in those columns as is. In this case, they should be of class “character”. Similarly, the “Dates” argument converts the indicated column to class “Date”.)
firstTestYr
and yearsSinceLastFirstTest
if(canWrite){
nmsNucWeapSt <- names(nWSdf)
if('firstTest' %in% nmsNucWeapSt){
firstTestYr <- lubridate::decimal_date(
nWSdf$firstTest)
yearsSinceLastFirstTest <- c(NA,
diff(firstTestYr) )
} else {
print(nmsNucWeapSt)
err <- paste("'firstTest' not in",
"names(nuclearWeaponStates)")
stop(err)
}
nuclearWeaponStates <- cbind(
nWSdf[, c('nation', 'ctry', 'firstTest')],
firstTestYr = firstTestYr,
yearsSinceLastFirstTest =
yearsSinceLastFirstTest,
nWSdf[, c('nuclearWeapons', 'nYieldNA',
'nLowYield', 'nMidYield', 'nHighYield')]
)
}
nuclearWeapons
Check the number of nuclearWeapons
if(canWrite){
nukes <- rowSums(nuclearWeaponStates[,
c('nYieldNA', 'nLowYield', 'nMidYield',
'nHighYield')])
dnuk <- (nuclearWeaponStates[,
'nuclearWeapons'] - nukes)
if(length(oopsNuk <- which(dnuk != 0))>0){
cat('count errors. bad rows =')
print(oopsNuk)
}
}
if(canWrite){
data(nuclearWeaponStates)
plot(yearsSinceLastFirstTest~firstTest,
nuclearWeaponStates, las=1,
type='h', xlab='', ylab='')
with(nuclearWeaponStates,
text(firstTest,
yearsSinceLastFirstTest, ctry))
}
… to svg
if(FALSE){
svg('Time2nextNuclearState.svg')
cex. <- 1.5
plot(yearsSinceLastFirstTest~firstTest,
nuclearWeaponStates, las=1,
type='h', xlab='', ylab='',
cex.axis=cex.)
with(nuclearWeaponStates,
text(firstTest, yearsSinceLastFirstTest,
ctry, cex=cex.))
dev.off()
}
if(canWrite){
cat('canWrite = TRUE')
save(nuclearWeaponStates,
file='nuclearWeaponStates.rda')
}
Then copy the *.rda file from the current working directory to “ecdat”, and run “R CMD check” as usual.
