Hi,
I need to run a script under the variable (that
comes from a csv file) that is assigned to another
variable. This is very a simplified version of what I
want to do:
data<-read.csv('name.csv')
names(data)<-("VA","VB","VC")
v<-VA
mn(v)
Thank you in advance,
Judith

I think you want: v <- data$VA On 7/2/07, Judith Flores <juryef@yahoo.com> wrote:> > Hi, > > I need to run a script under the variable (that > comes from a csv file) that is assigned to another > variable.

This is essentially a list with named components. So VA is not yet available as a variable in your program. The data for the variable you want to call "VA" is stored as the component 'data$VA' of 'data'. The names "VA", "VB", "VC" are the names you have given to the *components* of 'data'; you have not created separate variables with these names. So you can assign the data for VA directly to 'v' with: v<-data$VA or (if you think you will need it later) create a variable VA using VA<-data$VA and, if you want a variable called 'v' as well, then: v<-VA Hoping this helps, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <ted.harding at nessie.mcc.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 03-Jul-07 Time: 00:32:40 ------------------------------ XFMail ------------------------------
