Dear R-users,
I am a new user for R. I am eager to lean about it.
I wanted to read and summary of the a simple data file
I used the following,
rel<- read.table("C:/Documents and Settings/ashta/My
Documents/R_data/rel.dat", quote="",header=FALSE,sep="",col.names=
c("id","orel","nrel"))
summary(rel)
Below is the error message,
rel<- read.table("C:/Documents and Settings/ashta/My
Documents/R_data/rel.dat", quote="",header=FALSE,sep="",col.names=
+ c("id","orel","nrel"))
Error in file(file, "r") : cannot open the connection
In addition: Warning message:
In file(file, "r") :
cannot open file 'file=C:/Documents and Settings/sewalem/My
Documents/R_data/rel.dat': Invalid argument
summary(rel)
Error in summary(rel) : object 'rel' not found
Does it need a library? Where can I get the library?
Hi Ashta,
If you have checked that the file "rel.dat" is really there where you
think it is, there is a nasty trick that Windows plays with many files.
For example, if you have created this file in Notepad and saved it, you
may find that .txt has been added to the filename. So the real filename
is "rel.dat.txt". Of course, Windows won't show you that unless you go
into Folder Options in Windows Explorer and turn off that "Hide known
extensions" option. This is a wild guess, but it has happened to me so
often that I am wary of it.
