Set allowEscapes = FALSE when reading. See the help page for more details.
There is perhaps an argument for changing the default for allowEscapes
under read.csv, especially as people have now changed that for
comment.char (in R-devel).

Yes, see
?jpeg
?bitmap
and as you didn't tell us your OS we don't know if these are available to
you.
jpeg(file=test.jpg)
boxplot(sample(100))
dev.off()
may well work.
'An Introduction to R' explains about graphics devices, including these.

You should put your SQL query in a variable, and use this variable in

Indeed. For the record, R has an limit of 1024 chars

Dear List,
why does as.data.frame(cbind()) transform numeric variables to

Foo - as.data.frame(cbind(x.1))

Without knowing your OS this is hard to answer (and is the wrong list for
the ESS question).
For Windows users, the packages part is covered in the rw-FAQ.
For Unix-alikes, it all depends how the update was done, but normal
package update mechanisms (such as RPM) will not wipe out previously

First, this is off-topic for R-help (see the posting guide, including the
non-use of HTML, please).
Second, the appropriate list needs to see exactly what the output was when
you did this. Remember R CMD SHLIB is a *make* facility, and quite
possibly the objects were not remade after changes.

It is described in `An Introduction to R' (the most basic R manual).
