help combining mtext and strwrap?
...ines. From what I know about mtext, it's really only meant for single-line labels, not paragraphs. Here's some sample code of the idea I'm trying to accomplish: notes=c("Repressible alkaline phosphatase, a glycoprotein localized to the vacuole; regulated by levels of inorganic phosphate and by a system consisting of Pho4p, Pho9p, Pho80p, Pho81p and Pho85p; dephosphorylates phosphotyrosyl peptides") par(mar=c(10,3,10,3)) image(as.matrix(c(1,2,3,4,5))) mtext(strwrap(notes, width=60), line=5, side=3) ..as you can see, the long text plots over itself and doesn't wrap....

' quote problem in reading lots of files at once
.... But when a2 has ' - then starting from there to the EOF all values are cluttered. Example: > a2[49] [1] "mRNA guanylyltransferase activity" > a2[50] [1] "polynucleotide 5-phosphatase activity\t1\t1\t0.0160650535501781\t0.0160650535501781\t0.0664390950962566\nribulose-phosphate 3-epimerase activity\t1\t1\t0.0160650535501781\t0.0160650535501781\t0.0664390950962566\n How can I escape the ' quote character when I read each file. So that I do not have the problem of clutter and my matrix is read well. Thank you.

Cleveland Dot plots: tick labels and error bars
..., I've been learning how to make a 2x2 paneled dotplot in lattice without any previous experience using lattice. my code thusfar is: nut<-read.table("/Users/colinwahl/Desktop/nutsimp_noerror.csv", T, sep= ",") attach(nut) nut1<-data.frame(Nitrate, Total_Nitrogen, Phosphate, Total_Phosphorus) nut1<-as.matrix(nut1) rownames(nut1)<-group ylimlist=list(c(0,10), c(0,10), c(0,0.25), c(0,0.25)) dotplot(nut1, groups=FALSE, horizontal=FALSE, scales = list(relation='free' ), ylim=ylimlist, ylab="Nutrient Concentration (mg/L)") I have two issues cur...

some help regarding combining columns from different files
Dear all, Here is my code which am using to combine 5th column from different data sets. Here is the function to do my job genesymbol.append.file <-NULL gene.column <- NULL readGeneSymbol <- function(files,genesymbol.column=5){ for(i in fnames){ temp <- read.table(fnames,header=T,sep="\t",stringsAsFactors=F,quote="\"")
