Question: Rgraphviz plot of bnlearn object with text too big

Hello, I'm starting to use the combination bnlearn and Rgraphviz, and it generates wonderful bayesian network plots! Congratulations! However I'm facing some strange issue: bayesian networks generated from some specific dataframe have text inside ellipses very big, and it's unformatting the plot. The commands I used are as follow: # load data frame d <- read.csv2("financ_auto.csv", row.names=1) # omit NA's d <- na.omit( d ) # Iterate all variables for(i in 1:ncol(d)) { if(is.numeric(d[[i]])) { # Categorize variable if it's numerical d[[i]] <- cut(d[[i]],5) } } # Generate bn object (graph) bn <- mmpc(d) # Generate pdf tf <- tempfile() pdf( tf, width = 20, height = 20) graphviz.plot(bn, shape="ellipse", layout="neato") tf The dataframe file and generated plot are on the following links: Does anyone knows what may be happening? Thanks in advance! Cheers, Joao D. Duarte UFMG - Brasil [[alternative HTML version deleted]]
