Hi Agus, Eh perhaps not - is there a more suitable list ? I thought sticking logos into maps would be common enough practice here ? I'm not sure gimp is a solution since it also depends on ghostscript. I'm starting to tihnk Adobe Ilustrator is my only option - which is irritating since I don't have it.
You want to add an image for which you have either JPEG or EPS versions available to base R plots? If you convert your JPEG to PNM, use: library(pixmap) ?"addlogo-methods" Consider using locator() to provide the anchor for the logo.
You might also find it easy to use the jpeg package. http://cran.r-project.org/web/packages/jpeg/index.html Cheers, Ben

James,
Are you sure this is the right list for this question?
I would rather use gimp for that purpose.

Anyone got experience with grImport even ?
I'm at my wits end with this. Think I'm going to have to just do it in photoshop or something after the fact.

Hi all,
I need to add a logo to a plot. I have the logo in eps and jpg formats though can convert it to something else if needed.
My preference is to use the eps version since I am plotting my graphs to an eps file.
However I'm having a problem - with grImport - it is not detecting all the features of the image (not picking up colours and missing internal features of plot.
My code is thus:
PostScriptTrace("LogoLarge.eps")
logo<-readPicture("LogoLarge.eps.xml")
Does anyone know why it is not catching all features of the image ?
Any other way of doing is ?
James
