Nesono-Bin Bashtils RM to Trash Now with Put Back Support

I just changed my helper script, which moves the specified files into Trash instead of deleting them directly to use the Finder by calling AppleScript.

A usable R-GUI under (Windows), Mac OS X, and Linux

Some days ago I found a nice GUI for R: RStudio! It works as it should always have been: with a workspace/data browser, script editor (with source on save), documentation viewer, file browser, and a plot view.

Yesterday, I needed to start spellchecking my latest paper and gave :help spell a try in vim. The following line made me almost completely happy:

:setlocal spell spelllang=en_us

After that, typos were highlighted with respect to the alleged error made and suggestions are queried using z= for the word under the cursor or the selection in visual mode. Alternatively, the word can be added to the list of accepted words by pressing zg.
