Hi again, Duncan
I think I must tell you all the details of the method I use, in order to
make possible you notice my error. However, you must know that this method
run on 3.0.1 version (not in 3.0.2 and not in 3.1.0; this is the problem!).
1) This is my code in "D:/probando.r" :
.ChrL.env <- new.env()
.ChrL.env$lGlo <- list()
.ChrL.env$bStarted <- FALSE
CheckGloCreated <- function() {
if (.ChrL.env$bStarted == TRUE) {
stop("Data structures were already initialized.", call.=FALSE)
}
}
ChrL.Start <- function() {
CheckGloCreated()
cat("Tested.\n")
}
2) I open RGUI and run the following:
setwd("D:/")
source("probando.r", encoding="utf-8")
package.skeleton(name="ChrL", path="D:/")
3) At this point, ChrL folder has been created in D:/, so I adjust
Description and Namespace files. In R folder, ChrL-internal.r file is as I
indicate below...
>>
>>
>> My Namespace:
>>
>> export(ChrL.Start)
>>
>>
>> My ChrL-internal.R:
>>
>> .ChrL.env <- new.env()
3) I go to bin folder (C:/Program Files/R/R-3.1.0/bin) and run the
following:
R CMD INSTALL D:/ChrL
R CMD check D:/ChrL
R CMD build D:/ChrL
R CMD INSTALL --build D:/ChrL
Consequently, zip is generated, and I load it in RGUI. Then I do
"library(ChrL)", but I see .ChrL.env does not exists. ¡In 3.0.1 version it
run ok!. What is the reason why in 3.1.0 version It does not exists?.
Thanks again.
Eva
