Dear All:


It was saved, but there was a space somewhere. So it works for me now.

I do have another similar problem.

I saved an R data file


save(datahs0csv,file="
F:\Fall_2017\5-STA574\2-Notes\1-R\1-R_new\chapter4-Entering_Data/datahs0csv2
.rda")

*The new R data file "*datahs0csv2.rda*" is in the directory.*

I tried to load the file "" to R, but I got an error message. Please see
below.

*load(file="F:/Fall_2017/5-STA574/2-Notes/1-R/1-R_new/chapter4-Entering_Data/datahs0csv2.rda")*
>
It seems for me that the file was loaded to R. But when I typed the data
name, it says that the not found.

> *datahs0csv2*

*Error: object 'datahs0csv2' not found*


with many thanks
abou
