R help - Sep 2007 - help with unit indication when plotting

Dear all:

Is there any one could tell me how I can represent Micro-molar as an 
unit of concentration when I plot with R(S-plus), I don't want write 
'uM' from keyboard, I am thinking to write it like in word, in word, 
people insert symbol for 'u' for uM. Am I clear? Thank you very much 
for your consideration and help.


Lu

see ?plotmath

you want to use "mu" for micro, as in
plot(1:10, ylab = expression(paste(mu, "M")))

Look at ?plotmath, could you use a greek mu for the micro part?

plot(1,2, xlab=expression(mu * M))

See ?plotmath for all the other neat things R can do in labels on plots.

Dear all:

I am curious how to generate high-quality plot and graph with R and 
input it into my word document. my plot was always generated in device 
2, when I save it as PNG, the quality is poor. Thank you very much for 
your consideration and time.

To obtain better results, use vectorial formats (eps, pdf, svg, etc.)
and not bitmapped formats (png, jpg, tiff, etc.). In case, you are
using MS Word (as it seems), use eps; it may not look great on screen,
but it will look perfect on paper.

I now rarely use Word; if the size of the wmf as fixed by the win.metafile 
is smaller
than the size of the page within the margins you should have no problem.

So for letter size 8.5 x 11 inches with 1 inch margins and allowing 0.5 in 
for a label
you coud have a landscape mode wmf size of height = 6 and width = 9

If you wanted a larger size you would have to use the format picture and 
?frame to
set the picture in Word

For pointsize see
? windows
or
?ps.options

Most/?all graphic devices have this argument.

It relates to the size of the font you are using.
I changed the pointsize as an example - you can use the default font size 
if it suits your graph.

Sometimes it is easier to change pointsize than other things.
