Can't save history using savehistory()
savehistory() history doesn't seem to be doing anything on my platform. Here's an example: ======================================= [R.app GUI 1.35 (5665) i386-apple-darwin9.8.0] [History restored from /Users/u0048513/.Rapp.history]
tail(readLines(file("~/.Rapp.history")))
[1] "?Matrix" "15*275/1024" "log10(2^32/4)" [4] "log2(10^6)" "library(ff)#" "ffload(\"ff/a\", rootpath=\"/tmp\")"
5+5
[1] 10
savehistory('~/.Rapp.history')
tail(readLines(file("~/.Rapp.history")))
[1] "?Matrix" "15*275/1024" "log10(2^32/4)" [4] "log2(10^6)" "library(ff)#" "ffload(\"ff/a\", rootpath=\"/tmp\")"

One suspicious thing is that there are exactly 512 lines in the file ? but in the R.app preference pane I have the max number of history items set to 1000, so perhaps that's a red herring.
