R help - Dec 2011 - Is it possible to "right align" text in R graphics?

Hello all,

The following line of code includes a right-to-left language text, yet the
R graphics engine displays it from left to right.  One problem this causes
is when there are parenthesis in the test, here is a basic example?

plot(1:10, main = "שלום (טקסט)")

Is there a way to make sure the text is displayed from right to left?

Many thanks for any suggestions,
Tal

I'm not sure if this is what you're after, but this function reverses
the
string, character by character and swaps parentheses around.

rev.string <- function(x) {
        revx.indiv <- rev(unlist(strsplit(x, "")))
        revx.indiv2 <- revx.indiv
        revx.indiv2[revx.indiv=="("] <- ")"
        revx.indiv2[revx.indiv==")"] <- "("
        paste(revx.indiv2, collapse="")
        }
plot(1:10, main=rev.string("?? (??)"))

Hi Tal

Thanks to an e-mail from David, I realized that non-Hebrew speakers will
not be able to know how a proper right-to-left output should look like
(sorry for not thinking about it myself...)

Here is some example code of how the output should look like vs how it
currently looks.
This is shown only for the main parameter, but the same issue will come up
when using ?title or ?text

Two points to mention again:
1) This is not a huge problem for me personally, but I believe that in the
long term, if such an issue can be fixed, it would have been nice.  It will
allow all of the right-to-left languages to use R for plotting in their own
language (That included, for example, all of the Arabic world...
http://en.wikipedia.org/wiki/Right-to-left ).
2) I fear that this type of issue needs to be handled by someone familiar
with the guts of the R graphics code.  I am not even sure if I should post
this here or on the R-devel mailing list.  Your advise will be very welcome.


Here is the example code:

par(mfrow = c(1,2))
plot(1:10, main = "שלום (טקסט)", sub = "The order of text is not
right to
left")
plot(1:10, main = "(שלום (טקסט", sub = "This is how the output
should have
looked like")

# A more complex example:
plot(1:10, main = "שלום (טקסט) מידע על Subject 1", sub = "The
order of text
is not right to left")
plot(1:10, main = " Subject 1 שלום (טקסט) מידע על", sub = "This
is how the
output should have looked like")

# An even more complex example:
par(mfrow = c(1,1))
plot(1:10, main = "שלום (טקסט) מידע על Subject 1 וגם קצת מידע על subject
2", sub = "The order of text is not right to left")
# I am not sure how to fix this actually...


Happy new year,
Tal
