Hi, dear all, I want to show numerical values with decimal points on the boxplots. Here is what I did: For example; x1<-rnorm(100,2,2); x2<-rexp(100); label<-rep(1:2, rep(100,2)) median<-round(c(median(x1), median(x2)),3) boxplot(c(x1, x2)~label, medpch=paste(median), medcex=1.2) It only shows the integers at the median position in the boxplots. How to make it show more decimal points pls? Thanks a lot. Lily NUS [[alternative HTML version deleted]]

Dear Rexperts, I am trying to add a '+' identifying the mean in a boxplot using the following sizelist <- split(size, grp) centers <- boxplot(sizelist, style.bxp = "att", medpch = "o", ylab = "Prostate Volume (cm3)") points(centers, unlist(lapply(sizelist, mean)), pch = "+") But, I get error Error in xy.coords(x, y) : 'x' and 'y' lengths differ which I do not understand. The data follows grp size...

Dear all, I am a total beginner in R, so sorry if this is the wrong place. I am using R 2.10.1 on a Mac (Mac OS 10.6.2). I have this small dataset : growth sugar 75 C 72 C 73 C 61 F 67 F 64 F 62 S 63 S I have no problem reading the table, or getting the summary, but if I try boxplot(growth~sugar, ylab="growth", xlab="sugar", data=Dataset), I have the following error :

...xysegments(xP(x, -wntch), stats[3L], > xP(x, +wntch), stats[3L], > - lty = medlty[i], lwd = medlwd[i], col = medcol[i]) > + lty = medlty[i], lwd = medlwd[i], col = medcol[i], lend=1) > xypoints(x, stats[3L], > pch = medpch[i], cex = medcex[i], col= medcol[i], bg = > medbg[i]) > ## Whiskers > > > > Best wishes, > Uwe Ligges > -- Brian D.
