Hi Kevin,

What is texscan? I never knew that, so I always just ignored the command ;)
Actually, it was tex.scan, which is a simple ruby command scanning the string given by the variable tex. I think Kevin by accident mistyped it. (You can see the revision diff).
What a difference a dot makes, eh?
OK. I changed it and now tex.scan works. (Actually I was a bit blind, the one thing I had to do is to read the ruby code ;) )
I like the command too, though I don't really use it much at this point, (need to open the actual help file most of the times). I wrote the command originally, and looking at the revision history of the command would show that it was tex.scan. Does it work as expected if you make that change? If so, I don't really see the advantage of parsing the HTML file instead.
Well, my HTML scan approach is to output everything which is written within the 'Usage' block.
Example:
##################### 'difftime'
tex.scan output: _________________ time1 - time2
html output: _________________ Usage:
time1 - time2
difftime(time1, time2, tz = "", units = c("auto", "secs", "mins", "hours", "days", "weeks"))
as.difftime(tim, format = "%X")
## S3 method for class 'difftime': round(x, digits = 0)
##################### 'matrix' tex.scan output: _________________ matrix(data = NA, nrow = 1, ncol = 1, byrow = FALSE, (??)
html output: _________________ Usage:
matrix(data = NA, nrow = 1, ncol = 1, byrow = FALSE, dimnames = NULL)
as.matrix(x)
is.matrix(x)
Well, the question is what does the user expect by using 'Command Usage'
By my opinion the tex.scan version is very similar to the Kevin's 'Insert Command Template'. So I would suggest to use the HTML version instead. This is a bit more informative.
On the other hand if we decide to use the tex.scan version then it would be better to change the line
file = `find "${R_HOME:-/Library/Frameworks/R.framework/Resources}"/ library -name #{text}.tex -print`
into
file = `find "${R_HOME:-/Library/Frameworks/R.framework/Resources}"/ library -name #{text}.tex -print 2>/dev/null`
to speed up it a bit
and
we have to fix the 'bug' for matrix(), for instance, to display the whole definition.
