Hi, I need to convert numbers to characters in order to index an array when I encountered the number 100000 which turned into "1e+05". Does anyone know how to get around this problem?

Hello, I'm doing some scripting and I've noticed that R doesn't seem to have an if (cond){ do }ifelse (cond) { do } else { do } type block. Is this correct or am I missing something. THX Paul -- Research Technician Mass Spectrometry o The / o Scripps \ o Research / o Institute

...uot;10" "40" Is there a way to take cc[i:index[i-1],] to another format as to where each block could be worked on separately. ie so in one block would be rows1:10 the next block would be rows11:40 and so on.

...I would like to compare two sets of count data which form Poisson distributions. I'd like to generate some sort of p-value of the likely-hood that the distributions are the same.

...lumns. If I find that the number in A[9,x] and B[9, x] are the same then I want to remove the row that it is comparing from A. So overall, if something appears in B then I remove it from A.

Hello everyone, I have an overlay plot it's nice but you can't see all the data. I would like to know if there is a way to get a plot that gives a side by side plot so that each plot would be next to each other. The two plots have the same data are of different species. At the moment this is the code I'm using: exp<-cbind(abs(round(rnorm(10),2)*10), seq(100, 200, by=10))

...C 500 400 200 1000 ^ | samples I would like to plot these however, all I get is a very messed up plot. It may be due to the size of the matrix, it is 7746 rows long. But I thought for R that shouldn't make a difference. Cheers, Paul Research Technician Mass Spectrometry ? o The ? / o Scripps ? \ ? o Research ? / o Institute

...I make a negative number positive. Such as -5 to be +5 I tried +(-5), but that didn't work. So no, I don't mean taking a -5^2 just to get a positive number. This is in a function so it's not just -5 it's x. :) Thanks, Paul -- Research Technician Mass Spectrometry o The / o Scripps \ o Research / o Institute
