Hi,
I need to use ggplot2 package for plotting my results. I could use it when I
just work with R but when I import it in my python program, I got this
message:
>>> import rpy2.robjects.lib.ggplot2 as ggplot2
Loading required package: ggplot2
Loading required package: proto
Loading required package: grid
Loading required package: reshape
Loading required package: digest
Error in eval(expr, envir, enclos) : could not find function "proto"
In addition: Warning messages:
1: In library(package, lib.loc = lib.loc, character.only = TRUE,
logical.return = TRUE, :
there is no package called 'proto'
2: In library(package, lib.loc = lib.loc, character.only = TRUE,
logical.return = TRUE, :
there is no package called 'reshape'
3: In library(package, lib.loc = lib.loc, character.only = TRUE,
logical.return = TRUE, :
there is no package called 'digest'
Error : unable to load R code in package 'ggplot2'
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File
"/usr/local/lib/python2.6/dist-packages/rpy2/robjects/lib/ggplot2.py", line
10, in <module>
ggplot2 = importr('ggplot2')
File "/usr/local/lib/python2.6/dist-packages/rpy2/robjects/packages.py",
line 82, in importr
raise LibraryError("The R package %s could not be imported" %name)
rpy2.robjects.packages.LibraryError: The R package ggplot2 could not be
imported
How could I manage to solve the problem?
Cheers,
Zahra.
