Hi,
I look at 'Insert Command Template' and this one of my favorites ;)
Nevertheless I have some humble suggestions to improve it:
1) Now this command executes the apropos function within a new fresh R session. This means that it doesn't know which libraries I'm currently using and it doesn't know which functions I defined within my R session. To use 'Insert Command Template' also for this you should load the function 'getSig.r' in my current session (renamed in '.getSig' ) and executes this within my session to get these signatures too. By doing so you would increase the speed of it enormously and you can insert signatures for user-defined functions and functions coming from loaded libraries. The disadvantage of it would be that you have such queries in your current session; ok you don't see them in the TM R console window, but if you save it workspace you would have these. To avoid this you could think about to write the answer of the query into a file and load it in TM. Or, if you don't interested in the user-defined functions you could start a new R session which loads all libraries which are loaded in my current session. (I don't know whether this would also work for user-defined fucntions?)
2) If you use the approach in 1) then you can do more elaborated things with it because of the speed. Examples: -If I look for for a keyword it will insert the signature like the old version. If there is nothing found it will look for functions which begins with the keyword like the old version. -If I type e.g. 'data.' it lists all methods for 'data.' like data.class, data.frame etc. but not 'dataentry' -If I type e.g. '.difftime' you get all functions where '.difftime' is specified like mean.difftime, print.difftime. To insert the signature you have to select the keyword in beforehand otherwise it shows a tooltip. -If I have no idea about the complete name of a function you can type e.g. '.load.'. This would look for '*load*' as regexp. Furthermore sometimes I cannot remember whether the a function is called 'shownames' or 'showNames', so you can write '.names.' and it looks for '*names*|*Names*'. I would use periods for '.foo.' for indicating this because it will be caught be Ruby's getword function.
Of course you can do more things: -You could catch the 'apropos()' function and run it in TM and print the result as pop down menu
and and and
What do you think about it?
To change to code would be relatively easy.
Best, -Hans
