[R] first readline() instance getting skipped on windows with R 3.3.3
hi, i'm curious if anyone else has noticed a change in behavior of
readline()?
i have a function in an R package that calls readline() here:
https://github.com/ajdamico/lodown/blob/master/R/mics.R#L126
after upgrading to 3.3.3, the function appeared to start ignoring that
readline() call. my function runs some internet and plotting commands, so
i might be doing something wrong here. i figured out that i can work
around the problem by adding an empty readline("") call earlier in the
same
function.. so readline() is just getting skipped at the first occurrence
for some reason. this line works around the problem, which seems odd:
https://github.com/ajdamico/lodown/blob/master/R/mics.R#L94
i've been unsuccessful reproducing this more succinctly. latest R news
indicates lots of changes to this function:

here's my extSoftVersion() and sessionInfo()
thanks!
