Hello everyone, I'm trying to port the following R code to rpy2:
plots<-ggplot(pz_r,aes(x=z))+geom_histogram(aes(y=..density..),binwidth=bw)+geom_line(data=zfunc,aes(x=z,y=dens)) where pz_r is a data frame of observations of the random variable z, and zfunc is a data frame with the probability density function (z and dens). Currently, I've been able to port the histogram more or less using: pp=ggplot2.ggplot(pz_r)+ggplot2.aes_string(x='z')+ggplot2.geom_histogram(ggplot2.aes_string(y='..density..'),binwidth=bw) However, I'm not sure how to get geom_line() to use the zfunc data frame: pp=pp+ggplot2.geom_line(zfunc,ggplot2.aes_string(x='z',y='dens')) I get Error: ggplot2 doesn't know how to deal with data of class uneval I'm using rpy2 2.1.0dev. Help with this would be much appreciated. Thank you.
