Dear All:
I am trying to load an R data set, but I got the following message. Please
see below. The file is there.
setwd("F:/Fall_2017/5-STA574/2-Notes/1-R/1-R_new/chapter4-Entering_Data")
datahs0csv <- read.table("hs0.csv", header=T, sep=",")
attach(datahs0csv)
detach(datahs0csv)
rm(list=ls())
Then I tried to reload the data, but I got this error message. I am not
sure what was wrong.
*> load("datahs0csv.rda")*
Error in readChar(con, 5L, useBytes = TRUE) : cannot open the connection
In addition: Warning message:
In readChar(con, 5L, useBytes = TRUE) :
cannot open compressed file 'datahs0csv.rda', probable reason 'No
such
file or directory'
Any help will be appreciated.
with thanks
abou

Hi Abou, You haven't saved the datahs0csv. When you are done manipulating datahs0csv you can use save(datahs0csv, file = 'datahs0csv.rda'). Then you should be able to load the data.

Hello, What makes you think that there is a file named "datahs0csv.rda"? You have not saved the file, in fact you have done nothing at all. If you want to create a file "datahs0csv.rda", use ?save. (And don't use 'attach', please.)

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 On Tue, Sep 12, 2017 at 2:53 PM, Ulrik Stervbo <ulrik.stervbo at gmail.com> wrote:> Hi Abou, > > You haven't saved the datahs0csv. > > When you are done manipulating datahs0csv you can use save(datahs0csv, > file = 'datahs0csv.rda').
