[R] trouble in setting jpeg a large size

[liuqi]

I met a trouble in setting jpeg a large size. for example, when i use
jpeg(height=65526), a problem "Error in devga(paste("jpeg:", quality, ":", filename, sep = ""), width,  : 
unable to start device devga In addition: Warning message: Unable to allocate bitmap" occurs.
 if a smaller size is set, no errors occur. 

 I'm using R 1.8.0 on win2k.

 Thank you for your help!
