i was trying to do a for loop for plotting the histograms , but it doesnt work properly
> library(lattice) > columns <- 8:153 > plots <- vector("list", length(columns)) > j <- 0 > for (i in columns) + { + plots[[ j <- j+1 ]] <- histogram( ~ data[,i] | data[,2],ylab = "Frequency", + xlab = "Score", xlim = c(1,5), ylim = c(0,100),layout=c(3,1), + main = c(colnames(data)[i],"index",j+1),mycolors = colors()[c(536,552,652,254,26)], + panel = function(..., col, mycolors) { + panel.histogram(..., col = mycolors[panel.number()])}) + trellis.focus('strip', 1, 1, highlight=FALSE) + ltext(0.60, -0.25, 'PPM', col='blue', pos=3) + trellis.unfocus() + } Error in grid.Call.graphics("L_downviewport", name$name, strict) : Viewport 'plot1.strip.1.1.vp' was not found > > print(plots[[1]]) I am not sure what was happeneing. . . can anyone help me ? ychu066 wrote: > > anyone know how to add text in the Trellis plot panel ?? i want to add > things eg: dot dot dot. in the headrer of the panel. > > eg: http://old.nabble.com/file/p26486579/hist1.png hist1.png > -- View this message in context: http://old.nabble.com/Trellis-Plot-tp26486579p26505934.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
