R Help:
I have read a number of tables into R with identical headings and I
would now like to make a single table that has all the data appended
under this single heading line.
for example:
t1 <- read.csv("f1",header=TRUE)
t2 <- read.csv("f2",header=TRUE)
all <- c(t1,t2)
#all is now twice as wide as t1 or t2 with the same number of row!!!!
#I need to know how to join these tables in a row wise fashion.
Can you help me?
Regards,
Bill

Does rbind() do what you want?
