Hi and thank you Why d&d directory onto R.app?
Now that I understand the common use of many Rdata's, one in each working folder, and Pref notes say "d&d of file or directory on R icon will override", I was trying to get with common usage by starting up with d&d onto R.app rather then double clicking R.app and then changing location; did not try to d&d a file since the R files (Rhistory and Rdata) are invisible; and then found that the "Always apply" directory is overridden; so then confused about what does "Always apply" mean This is part of my "prefs are confusing" problem but not part of the "Rhistory commands being forgotten" problem; which is probably more important Today I said I would stop fiddling with Rhistory and do work, but I find if I double click on the bottom entry in the history window, things go wrong. Seems like returns are added and multiple commands are combined into one entry in the file. Here is what the end of the history file looks like in BBEdit .Machine$sizeof.pointer sessionInfo() ls() rm (ABeset_gcrmaNumhom) ls() AB_gcrmaNumhom <- gcrma(AA_ReadAffyNumhom, fast = FALSE) library(gcrma) .Machine$sizeof.pointer# .Machine$sizeof.pointer# # .Machine$sizeof.pointer# .Machine$sizeof.pointer# # .Machine$sizeof.pointer# # # .Machine$sizeof.pointer# > From: Rob Goedman <robjgoed...@me.com> > Date: Wed, 06 May 2009 08:02:29 -0700 > To: Loren Engrav <eng...@u.washington.edu> > Cc: "r-sig-mac@stat.math.ethz.ch" <r-sig-mac@stat.math.ethz.ch> > Subject: Re: [R-SIG-Mac] R.app history forgets > > Loren, > > I will look into the 'Always apply', your understanding is correct and > it should not change the working directory on drag&drop of a file or a > directory if 'Always apply' is selected (according to my own note :-). > It seems to work fine for a file but not for a directory. > > Simon, do you recall if there was a specific reason why we treated > files and directories similar?
