     Hi,
     In  boxplot(),  is there a simple way to change the box colours for
     varifying
     no. of columns.

   One option:
   boxplot(file [,2:75], las=2, cex.axis=0.6, col=c(1,2,3,4,5,5,6,6,6))
   where the first four columns will be different colours, then the next two
   will be the same colour, then the next three (etc).

     In a different attempt, I could do the change of colour, for say,
     after every 14th column, like this -
     boxplot (file [,2:75], las=2, cex.axis=0.6,col = rep(seq(ncol(file)) + 1,
     each = 14))
     Now, wonder how to give different column-colors (red, blue, etc.) for
     varying sets of columns (e.g., color for the first 7 dataset = green, next
     4
     datasets = blue ... and so on).
     Many thanks !
     Cheers,
     Chintanu
