R help - Dec 2005 - column name of a table

hy all,

I wish to switch in a part in my code that use "read.table" to
"scan", actually i use this:

tab<-scan("data.dat",what=integer(),skip=1)
dim(tab)<-c(75,length(tab)/75)
tab<-t(tab)

It gives me a new tab with 75 columns, but i when i was using read.table with
headers then attach i could use the columns names to access the data values, now
how can i attach the columns names that are on the first line of the file
data.dat?

Any help would be great!

thks all
guillaume.

I am not sure to understand what you want, but maybe
colnames() is what you want.
for example
> mat
     [,1] [,2] [,3]
[1,]    1    3    5
[2,]    2    4    6
> colnames(mat)<-c("col1","col2","col3")
> mat
     col1 col2 col3
[1,]    1    3    5
[2,]    2    4    6


was it what you were looking for ?

florence.
