Hi I am really new using R, so this is really a beginner stuff! I
created a very small data set on excel and then converted it to .csv
file. I am able to open the data on R using the command "read.table
("mydata1.csv", sep=",", header=T)" and it just works fine. But when I
want to work on the data (e.g. calculate the mean of variable "X") R
says "object not found". I tried the "attach" command or "mean
("mydata1.csv"&X)" but still I get the same error message. I don't
understand why R is having difficulty finding a variable. I believe I am doing
something wrong. I will really appreciate if you could help me
with this.
