Hello, I'm trying to save a graph as a .ps file to include it in a LaTex presentation, but R replies:
Error: Invalid font type In addition: Warning messages: 1: font family not found in PostScript font database 2: font family not found in PostScript font database If I load the package grDevices and type "postscript()" then I can save it, but it creates also a text file saying: %%[ Warning: Helvetica not found, using Font Substitution. Font cannot be embedded.]%% %%[ Warning: Helvetica-Bold not found, using Font Substitution. Font cannot be embedded.]%% If I open it, I can see that it has changed the font, and often the text doesn't match the boundaries. Can you help me?
