'else' to avoid a syntax error in entering a 'if ... else'
construct at the keyboard or via 'source'.
but there's no syntax error when you break the line between "}" and
"else" in a function, e.g.
f = function(x) {

Line breaks in mathematical formulae in Rd files (PR#13287)
Hi,
This is a problem about writing R documentation (R-exts 2.6). The
command "\deqn" defined in "Rd.sty" is:
\newcommand{\deqn}[2]{\[#1\]}
which will put mathematical formulae in the "displaymath" environment;
that means line breaks are not allowed (or will not be shown) in
formulae, but sometimes we do need multiple lines of formulae. One
solution is to write

How to get commands history as a character vector instead of displaying them?
Hi Everyone,
I want to get the commands history as a character vector instead of
just displaying them, but the function history() just returns NULL. I

Special characters in Rd example section will cause errors
Hi (Duncan?),
The other day I noticed some characters will cause errors in R CMD
CHECK because of parse_Rd(), and AFAIK, these chars include '%', '{'
and '}'. For example, note the comments in the example section:
%~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~%
\name{testfun}
\Rdversion{1.1}
\alias{testfun}
\title{
A Test
}
\description{
A test
}
\usage{
testfun()
}
\value{

I need help creating a bubbleplot, like a simple pseudo three dimensional scatterplot of circles whose sizes index a 3rd variable. I initially came across this at http://addictedtor.free.fr/graphiques/graphcode.php?graph=73 but the circleplot function does not exist in fbasic as listed in the document.

How to obtain a sequence of dates consisting of only weekdays
Dear R-users,
How do I obtain a sequence of dates consisting of only weekdays without the weekends in R?
In S, I can do the following:
timeSeq(from="12/17/2007", to="8/25/2008", by="weekdays")
I tried using looking at timeSequence (fSeries package) and seq.Date (base package) but I do not know if I can specify "weekdays" rather than "day".

Write multiple objects / data frames into a single .csv -- write.csv
Hello,
Is there a way to put multiple data.frames or objects into a single .csv ?
I know I can use sink() to do this for a text file. Is there way to do it
for a .csv?
e.g. for sink()
sink("c5.k.s.p.92.LN.sl.vs.mean.txt")
symnum(c5.k.92.LN.sl.vs.mean)
symnum(c5.s.92.LN.sl.vs.mean)
symnum(c5.p.92.LN.sl.vs.mean)
sink()
Could I put these all into a single .csv, in a similar format to

outlier and whisker in boxplot
Hi, Dear R-users:
Sorry for bothering your guys again. I think I should rewrite my question.
I know how to extend whisker by using range. The question is that I will set
the range=1.5, and at the same time, I only want to show the extreme
outlier, like 0.01% and 99.99% percentile, so what should I do?
Thank you very much!
