...er(1)) returns true However, I can't use as.integer, because it is too aggressive for just error checking: it rounds off the value to the greatest integer less than. Can anyone suggest a suitable method of checking for an integer in this case?

...can you suggest a version it *would* compile correctly with? It is possible the configure file could be tweaked to perform correctly, but how? I heard this compiles correctly on OpenSSH.

...owever, the plot appears in totally the wrong position. I know this is not an R question as such, but the eps file is produced by R and I thought that perhaps other people had had similar problems and could give me pointers.

Dear R people, The header practically says it all. I was wanting to include r code in a Latex file. Since R code using{ and }, which are interpreted by Latex as control characters, I would expect it to get upset. I believe that \{ would probably print as {, but I hoping I don't have to go through the code and add lots of \. I would rather use some global commannd, along the lines of

Dear People, In a qqplot I am doing, I get lines/points that are very thick. I've tried setting the lwd variable to 0.1, but it doesn't seem to have any effect. Also, I have set the value of lty to dashed, but I still get dots. The command looks like qqplot(cdf.inv(seq(0,1,length=size),theta,pos,len),empmargdistvec(len,theta,pos,size), xlim=c(-theta,theta), ylim=c(-theta,theta),
