70% yes, the problem is i am trying to produce a graph similar to the one in attachments in this message, which represents the frequency of each letter "aminoacid" in the cleaved function and the noncleaved function. some thing else i added to the attachments is the pattern which seemingly working correctly, i am trying now to create a R code to loop and simulate this pattern in order to draw all rectangles for the eight columns. But i don't know exactly how to deal with this variable which i highlighted with yellow in the image, it is cumulative in a challenging way. http://n4.nabble.com/file/n1290048/cleaved.jpg cleaved.jpg http://n4.nabble.com/file/n1290048/pattern.jpg pattern.jpg -- View this message in context: http://n4.nabble.com/More-than-on-loop-tp1015851p1290048.html Sent from the R help mailing list archive at Nabble.com.
