Many thanks for your advise, Sarah!
I will try to implement it. (Now I will have to change all my reading and
writing sentences of all my functions, because they read/write from/to
the users working directory...)
Whcih is OK if the user specifies some filename.
Best,

Best regards,

Don't change the working directory! That has all kinds of unpleasant
side effects for the unsuspecting user, possibly even more so than
writing to a file.
Instead, write the file to the temp directory, and read it from there,
with e.g.
wd <- tempdir()
write(dat, file.path(wd, 'Ttest_1981-2000.dat'))
Using file.path() means that the appropriate path delimiter for that
OS will be used.

Dear all,
I am struggling to update my package climatol from version 3.0 to 3.1.
The old version had all examples under a "dontrun" section because they
needed files created by other examples that the user had to run first.
As this is not acceptable anymore, I made the examples runnable and
prepared small ad-hoc datasets, but then writing files to the user space
is against the CRAN policy rules, and I was suggested to run them on a
temporal directory. Therefore I changed all my examples to read/write
files to a tempdir(), as in:
\examples{
#Set a temporal working directory and write input files:
wd <- tempdir()
setwd(wd)
data(Ttest) #(This loads matrix 'dat' and data.frame 'est.c')
write(dat,'Ttest_1981-2000.dat')
write.table(est.c,'Ttest_1981-2000.est',row.names=FALSE,col.names=FALSE)
rm(dat,est.c) #remove loaded data from memory space
#Now run the example:
dd2m('Ttest',1981,2000)
#Input and output files can be found in directory:
print(wd)
}
But now CRAN checks return this warning ten times (one for every example
in the package):
Warning: working directory was changed to ‘/tmp/RtmpWSRK2F’, resetting
Any hint on how to solve the problem will be highly appreciated...
Jose
