I'm trying to rbind two data frames, both with the same columns names. One
of the columns is a variable with date-time and this variable is causing the
rbind to fail--giving the error
"Error in names(value[[jj]])[ri] <- nm : 'names' attribute [7568] must be
the same length as the vector [9]"

Hi All,
I have a problem with rbind.
I have data that consist of weight height .. etc of 1000 patients. I would
like to find the mean and the standard deviation ( for the weight , height
etc) for each gender.
data<-read.table("data.txt", header=T, sep='\t')
fdata=NULL
for (i in 1:50){
nn<-na
Try 'check.names=FALSE' in the read.table call.

I am trying to use rbind to have the two data on the top of each other but I
am getting an extra X on the column header and the rows are numberd , How to
get rid of this problem? I appreciate your help
x1<- read.table(file="data1.txt", header=T, sep="\t")
x2<-read.table(file="data2.txt", head
