cummeRbund error

[TPH]

Hello,

After completing all the analysis steps from Tophat to Cudiff, I am trying to plot the data using CummeRbund. But I get this error message saying "semi-transparency is not supported on this device: reported only once per page".
I work in a cluster using Linux and use R/3.2.2 compiled with Cairo. Could you please help me to fugure out the issue here.

These are the commands and their outputs I received.

$ module load R/3.2.2
$ R

>library(cummeRbund)
>cuff_data <‐ readCufflinks('/Path to cuffdiff output folder/cuffdiff_out')
>csDensity(genes(cuff_data))

Removed 8804 rows containing non-finite values (stat_density).
2: In grid.Call.graphics(L_polygon, x$x, x$y, index) :
semi-transparency is not supported on this device: reported only once per page



---------------------------------------------------------------

I feel like there is an issue with the cummeRbund loading. But I can't figure out what is it. This is the output I get when cummeRbund Loads.
