Does anyone have any recommendations for producing dotplots with error bars? Are there packages available for this? I searched far and wide and cannot find a suitable option. I am trying to produce publication-quality figures for my thesis results. Dotplots (Cleveland dotplots) are a much better form of summarizing barchart-type data. It does not appear that any of the main plotting packages in r

I would rather use cleveland dot plots than bar charts to display my study results. I have not been able to find (or figure out) an R package that is capable of producing the publication quality dot charts Im looking for. I have either not been able to get error bars (lattice), cannot order the data display properly (latticeExtra), or cannot make adjustments to axes. Does anyone have a quick

Hello, I'm using range do define boundaries for a linear model, so the line I graph is only graphed for the range of data. There are NAs in the data, but I dont remember this being a problem before. I typed na.action=na.omit anyway, which has usually solved any NA issues in the past. Any idea why R cant do vector functions for these data? Solution? Thanks, Colin Wahl M.S. Biology candidate

Dear list, 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

Hi all, I think I may be confused by different people/programs using the word rotation differently. Does prcomp not perform rotations by default? If I understand it correctly retx=TRUE returns ordinated data, that I can plot for individual samples (prcomp()$x: which is the scaled and centered (rotated?) data multiplied by loadings). What does it mean that the data is rotated from the
