[R] ggplot2-Problem (plot different variables)

[ONKELINX, Thierry]

Try something like this

library(ggplot2)
data<-as.data.frame(cbind(a=c(1,1,2,2,2,2,3,3,4), b=c(1,2,3,3,4,4,4,4,4)))
library(reshape)
Molten <- melt(data)
ggplot(Molten, aes(x = value, colour = variable)) + geom_density()

Best regards,

Thierry

To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of.

The combination of some data and an aching desire for an answer does not ensure that a reasonable answer can be extracted from a given body of data.

Hi everyone!

I have the following difficulties using ggplot2

# My Data
data<-as.data.frame(cbind(a=c(1,1,2,2,2,2,3,3,4), b=c(1,2,3,3,4,4,4,4,4)))

And I would like to plot the frequency-distributions of both variables in one plot as lines. For both variables the values (1-4) should be on the x-axys and the frequency on the y-axis.

I have already found out, that this should work (somehow) using
stat_summary()

Can anyone help me?

library(ggplot2)
p<-ggplot(data=data, aes(a,b) )
p+stat_summary(??)

Thank you very much for help!
David
