Hi, I'm trying to construct a legend which has four lines of text and associated symbols. The first two symbols need to be normal lines which vary only in colour. The second two symbols should have filled boxes. How do I suppress the fill boxes in the first two lines? J.

Hi all, I'm writing a function that will automatically generate a report based on answers to a questionnaire. The exact questions and answers to the questionnaire can vary. One of the question types is in a "matrix" format, where the agreement to several statements can be indicated on a scale. I'm planning to plot this on a multilevel barplot, and only labeling each "bar

Hi R Users, I tried to increase the legend height in ggplot2, but it did not respond at all using the follwoing code. Do you have any suggestions for me? dat<-data.frame(temperature) P1<-ggplot(dat, aes(X, Y)) Scenario1<-P1+geom_point(aes(colour = value), size = 1)+ theme_bw()+ theme(axis.text.x = element_blank(),axis.text.y = element_blank())

Hi All, I am trying to build a composite plot, with multiple categories, using ggplot2. In principle, it could be done using facetting, but I do not seem to be able to get past the defaults, so I try building each plot separately, then putting them all together using frameGrob and placeGrob. For this, I need to know how to: 1) format the legend with a different layout (e.g 2 rows by 2 columns,

Hi: The y axis on the hist function seems to set its limits oddly. sometimes, it covers the full range of the data and sometimes it stops one major tick short. I have had this behavior with a variety of data sets, and it can easily be reproduced by just running the following several times: hist(rnorm(100000)) I have tried explicitly setting ylim to the range of values produced by rnorm

Hi , I would like to use ggplot2 to plot a matrix as an image. You can copy paste the following Data<-matrix(data=rnorm(900,80,20),nrow=30,ncol=30) lengthOut<-5 Lengths<- 15 library(reshape2) library(ggplot2) tdm <- melt(Data) ggplot(tdm, aes(x = Var2, y = Var1, fill = factor(value)),levels=seq(0,1,by=0.1)) +                   labs(x = "MHz", y =
