Re: [R] add data to a file while doing a loop

[Sander Timmer]

So you're looking for:

write.table(dataset, file=x.txt, append=TRUE)

Or do I understand your question wrongly?

Re: [R] Regular expression substitution ...

[Sander Timmer]

It's a bit strange:

 sub(/pc, '\\%', x)
[1] %

 sub(/pc, '%', x)
[1] \\%

Also with fixed I'm not able to get a single \ as return value.

I would like to replace all occurences of

   /pc

with

  \%

using something like

sub(/pc, \%, x)

but I am unable to make the '\' pass through.

Any hint?

Thanks,

Roberto
