Hi,

sapply((1:NCOL(hermes)),function(x) hist(hermes[,x],main=names(hermes)[x]))

.......this works , but i would like use it with apply to generate many plots in one step!

####################################################################

>>apply((1:ncol(hermes)),2,function(x) hist(hermes[,x],main=names(hermes)[x]))
Error in apply(1:ncol(hermes), 2, function(x) hist(hermes[, x], main = names(hermes)[x])) : 
        dim(X) must have a positive length

>>apply(hermes[,1:6],2,function(x) hist(hermes[,x],main=names(hermes)[x]))
Error in hist.default(hermes[, x], main = names(hermes)[x]) : 
        `x' must be numeric

>>apply(hermes,2,function(x) hist(hermes[,x],main=names(hermes)[x]))
Error in hist.default(hermes[,x ], main = names(hermes)[x]) : 
        `x' must be numeric


thanks for advance & regards
