Thank you for your answer. According to the help, they are suggesting to use "layout" which I did.
However, font size is still reduced by the same factor. Here's my code: pdf(file="Fig5.pdf", width = 4.86, height = 6.29, family ='Times') nf = layout(matrix(c(1:4), 2, 2, byrow = TRUE)) par(ps = 22) hist( rnorm(100) ) hist( rnorm(100) ) hist( rnorm(100) ) hist( rnorm(100) ) dev.off() -- View this message in context: http://r.789695.n4.nabble.com/Font-size-R-tp3745762p3747069.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
