Dear all,
I have a rather complicated problem. I am trying to loop through making graphs,
so that the graph-making process is fully automated. For each graph, I'd like
to
make sure the corresponding title is formatted properly. The titles will be a
combination of a gene name and numerical position within the gene. The gene
name
should be italic-bold, whereas the gene position should be just bold.
Consider the following:
x <- read.table(textConnection("gene position
FLC 3312
TFL1 687
GA1 1127"), header = TRUE, as.is = TRUE)
closeAllConnections()
Now this, below, is essentially how I am automating the graph-making (imagine
these graphs contain some sort of real data):
par(mfrow = c(3,1))
for (i in 1:nrow(x)){
plot(z <- sort(rnorm(47)), type = "s", main = "")
points(z, cex = .5, col = "dark red")
title(main = paste(x[i,1], " p", x[i,2], sep = ""))
}
The graphs produced by this method are almost perfect, except that the gene
names are not italicized (they SHOULD be).
So, once again, the big question is: how would I italicize the gene names but
NOT the gene positions, when looping through to make these graphs and graph
titles? If I WASN'T looping to make my graph titles, I could write:
title(main = expression(paste(bolditalic("FLC"), bold("p3312"), sep = " ")))
...but I can't do that, because I'm looping (or can I?)
Thanks in advance for your help!
