And if that's not enough:

library(pastecs)
data(trees)
t(stat.desc(trees))
?stat.desc

df2 <- df[ , -c(1, 3), drop = FALSE]

for instance to eliminate variables in columns 1 and 3, but there are 
many other ways to select variables to use in an analysis, beginning 
with the formula interface, see,  e.g., ?lm.

See also functions in the Hmisc package.

See ?pdf

Please, note first search commands:

apropos("pdf")
RSiteSearch("latex")

Using these, you would have found by yourself the various corresponding
