[R] Unable to save plot as ".pdf" , "ps" , "eps"

[Luis Ridao Cruz]

R-help,

Whenever I try to save a plot with extension ".pdf" , "ps" or "eps"
I get the following error/warning message:

plot(rnorm(10))
savePlot("test",type="pdf")

Error in savePlot("test", type = "pdf") : Invalid font type
In addition: Warning messages:
1: In savePlot("test", type = "pdf") :
  font family not found in PostScript font database
2: In savePlot("test", type = "pdf") :
  font family not found in PostScript font database


Can anyone let me know wht it is going on

Thanks in advance
