Hi - I am not familiar with R. Could I ask you a quick question?
When I read a file like this, I get an error. Not sure what I am
doing
wrong. I use a MAC. How do I specify a full path name for a file
in R? Or
do files have to reside locally?
KoreaAuto <- read.table(""/Users/
I think the opening and clsing quotes meant that you supplied an empty
string to the file argument.
raviramaswamy/Documents/Rutgers/STT 586/HW1 Data.txt"")
Error: unexpected numeric constant in "KoreaAuto <-
read.table(""/Users/raviramaswamy/Documents/Rutgers/STT 586"
Using single instances of either sort of quote ( " or ' ) on the ends
of strings should work. If you drag a file from a Finder window to the
R-console you should get a fully specified file path and name.
Seems like the working directory is
getwd()
[1] "/Users/raviramaswamy"

meminfo.csv", sep=",", header=TRUE)

4 4 3033332 3150004 4.5

You can also shorten the Users/<username> part to "~"
> rd <- read.table(file="~/Downloads/meminfo.csv", sep=",",
header=TRUE)
so I said this and still got an error
KoreaAuto <- read.table(/Documents/Rutgers/HW1Data)
Error: unexpected '/' in "KoreaAuto <- read.table(/"
But using no quotes will definitely not work. (And that was not a full
path name anyway.)
Could someone please help me with the correct syntax?
Thanks
