A minimal R source code file producing this is:
data=c(1,2)
pdf(file="error.pdf")
barplot(data)
legend(1.5,c(expression(italic("C.sativa"),italic("B.rapa"))),horiz=TRUE)
dev.off()
The problem is that the two italicised strings are not aligned in the pdf
output, with the string on the left being lower than the string on the right by
size of about two dots. Removing the calls to expression and italic produces
correct alignment, but italic is required in the final figure.
The R version information etc. follows.
