I am running a loop. Warnings sometimes occur, and the lop continues
until the end.
For each iteration of the loop, I wish to capture and "save" any
warnings issued, so that I can tell on which iteration the warnings
were issued.
I tried this, but it does not work.
mylist <- list(NULL)
mylist_warns <- list(NULL)
old.warn <- options(warn=1)
x <- c(1:5)
for (i in 1:2) {
assign("last.warning", NULL, envir = baseenv())
mylist[[i]] = x[ (i:1): 5 ]
mylist_warns[[i]] = warnings()
}
mylist
mylist_warns
