I'm not looking for specific code, just sort of a list of the common

except for the first and last? (I know you can achieve this using two

To scale more than one variable in a concise call, consider something
along these lines:
apply(iris[,1:4], 2, function(x){ave(x, iris$Species, FUN = scale)})
hope this helps,

but isn't there something more streamlined? My first guess was
y=c(2,3)
which(x==y)

which doesn't work. I haven't found any clue in the R manual.
How about this?
which(x %in% c(2,3))

try:
xx[,-x2]
Error in -x2 : invalid argument to unary operator
things don't work. Is there a simple way to do this by name rather
than number, please?
Another way to do it is with subset():
subset(xx, select = -x2)
Thanks,

Guide asks, you can use RSiteSearch() or help.search()
before posting to search for functionality. For example:
RSiteSearch('merge', restrict='function')
The third hit points to merge(), which does what you want.

and supply the url as an argument to htmlTreeParse(), but I don't know
how to go from there.
