Hi all, I am stuck at ploting multiple graphs on one page. I don't why it doesn't work.
All the 6 plots are either exactly the same, or they simply don't plot at all. I made sure that in each iteration the "datasub" and "factorsub" are different ... Could you please help me? Thanks a lot! I did my homework and followed the following advice: http://stackoverflow.com/questions/1249548/side-by-side-plots-with-ggplot2-in-r my.multiplot <- function(..., plotlist=NULL, cols) { require(grid) # Make a list from the ... arguments and plotlist plots <- c(list(...), plotlist) numPlots = length(plots) # Make the panel plotCols = cols # Number of columns of plots plotRows = ceiling(numPlots/plotCols) # Number of rows needed, calculated from # of cols # Set up the page grid.newpage() pushViewport(viewport(layout = grid.layout(plotRows, plotCols))) vplayout <- function(x, y) viewport(layout.pos.row = x, layout.pos.col = y) # Make each plot, in the correct location for (i in 1:numPlots) { curRow = ceiling(i/plotCols) curCol = (i-1) %% plotCols + 1 print(plots[[i]], vp = vplayout(curRow, curCol )) } } My code is as below: ---------------------------- myplotlist=vector('list', 6) nCount=0; for (j in myyears) { print(j) nCount=nCount+1 #... # prepare datasub and factorsub for different j... #... tmp<-data.frame(as.double(datasub),as.numeric(factorsub)) tt=qplot(factor(as.numeric(factorsub)),as.double(datasub),data=tmp,geom = "boxplot",ylab='Chg',xlab='Hours', main=j) myplotlist[nCount]=tt } my.multiplot(plotlist=myplotlist,cols=3) ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
