Simultaneously adding rows and columns by '[<-.data.frame' may fail
...j' is meant instead of 'j'.
In the code of function '[<-.data.frame', near the end, it looks like 'j' needs to be replaced with 'jj' in the lines marked by # below.
if (has.i)
for (jjj in seq_len(p)) {
jj <- jseq[jjj]
vjj <- value[[jvseq[[jjj]]]]

unexpected '[<-.data.frame' result
Is this a bug?
If not, I am curious to know why '[<-.data.frame' was designed to yield
a.frame$y != a.frame$z rather than refusing to carry out the operation at
all.
> a.frame <- data.frame( x=letters[1:5] )
> a.frame[ 2:5, "y" ] <- letters[2:5]
> a.frame[[ "z" ]][ 2:5 ] <- letters[2:5]
> a.frame

Transfer Crosstable to Word-Document
# Dear list,
# I am an R-beginner and
# spent the last days looking for a method to insert tables produced

# an SPO-file and paste it into a word document
# (if needed do some formatting with that table).
# Annother idea was, to produce a TEX-file,
# insert it and make it a word-table.
# I found the following libraries, which
