Dear List members, I wonder any person tried displaying Chinese labels with Rgraphviz. Typically, one saves the dot file with Chinese labels in UTF-8, and issue command "dot -Nfontname=simsun filename.dots -Tpng -o filename.png" in dos windows. The png picture would display the Chinese characters correctly. But the same trick seems failed in Rgraphviz. >library(Rgraphviz) >set.seed(123) >V <- paste(letters[1:5],"test??",sep="") >M <- 1:4 >g1 <- randomGraph(V, M, 0.2) >graph.par(list(graph=list(charset="latin1"), nodes=list(col="red", fontname="simsun"))) >g <- layoutGraph(g1) "Error: Invalid 2-byte UTF8 found in input. Perhaps "-Gcharset=latin1" is needed?" And the R session collapsed again. WIth the following codes, there is no error, but the label displayed with stranged characters instead of Chinese charaters. >library(Rgraphviz) >set.seed(123) >V <- paste(letters[1:5],"test??",sep="") >M <- 1:2 >g1 <- randomGraph(V, M, 0.2) >plot(g1, attrs=list(graph=list(charset="latin1"), node=list(fontname="simsun"))) I wonder whether it is possible for Rgraphviz to display Chinese characters correctly. Any suggestion would be appreciated.
