[igraph] postscript and label.family

[Vincent Matossian]

  Hi,

I'm experiencing this error when saving a plot as postscript:

Error in text.default(x, y, labels = labels, col = label.color, family = label.family,  : 
        family 'serif' not included in PostScript device

Even though names(postscriptFonts()) shows that "serif" is included first!

> names(postscriptFonts())
 [1] "serif"                "sans"                 "mono"                 "symbol"              
 [5] "AvantGarde"           "Bookman"              "Courier"              "Helvetica"           
 [9] "Helvetica-Narrow"     "NewCenturySchoolbook" "Palatino"             "Times"               
[13] "URWGothic"            "URWBookman"           "NimbusMon"            "NimbusSan"           
[17] "URWHelvetica"         "NimbusSanCond"        "CenturySch"           "URWPalladio"         
[21] "NimbusRom"            "URWTimes"             "ComputerModern"       "ComputerModernItalic"
[25] "Japan1"               "Japan1HeiMin"         "Japan1GothicBBB"      "Japan1Ryumin"        
[29] "Korea1"               "Korea1deb"            "CNS1"                 "GB1"                


I'm only having this problem using igraph but it might not be related to it, so I'm sorry if this is actually off topic.

But if anyone has had this problem or how I could fix it that would be great because this is preventing me from saving to .ps 


Thanks!

Vincent

PS (the other one): this is igraph 5.0 and R 
2.5.0. same problem on windows and mac.
