[R] Problem with converting F to FALSE

[arun]

Hi,
Try:
dat1<-read.table(text="
sex  group
F       1
F       2
F       3
",sep="",header=TRUE,colClasses=c("character","numeric"))
 dat1
#  sex group
#1   F     1
#2   F     2
#3   F     3


#if you are using read.csv()
 dat2<-read.csv("new1.csv",sep="",header=TRUE,colClasses=c("character","numeric"))
 dat2
#  sex group
#1   F     1
#2   F     2
#3   F     3


#Suppose you want to convert after reading it:
 dat2New<-read.csv("new1.csv",sep="",header=TRUE)
 dat2New[,1]<-substr(dat2New[,1],1,1)
 dat2New
#  sex group
#1   F     1
#2   F     2
#3   F     3

Hi, 
I have a peculier problem in R-Project that is when my CSV file have one 
column with all values as 'F' the R-Project converting this 'F' to FALSE. 
Can some one please suggest how to stop this convertion. Because I want to 
use 'F' in my calculations and show it in screen. for example my data is 
like 

sex  group 
F       1 
F       2 
F       3 

but when I use read.csv and load the csv file data is converting it to 

sex          group 
FALSE       1 
FALSE       2 
FALSE       3 
but i want it as source data like 

sex group 
F      1 
F      2 
F      3 


Thanks in advance,
