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
