Hi everyone,

plese can you look at this few lines :

data(iris)
res<-apply(iris,MARGIN=2,is)
res[1,]

the result is :
Sepal.Length  Sepal.Width Petal.Length  Petal.Width      Species
 "character"  "character"  "character"  "character"  "character"

How can I conserve the type off each colum? apply seems to convert it into
"character" adn it could be a problem for me.


Regards
