I read a csv file (with read.csv) containing missing values (as shown
below). Is there a convenient way to set these NA into zeros?
Better yet, is there an option to assign zeros to these blank cells in
reading the csv file? Thank you!
NA -1 NA NA NA 1 NA
NA NA NA NA NA NA NA
NA NA
However, be careful, because .Rprofile runs before any saved .RData file
is loaded. If the object you created in .Rprofile is later saved when you
quit R, then the next time you start R, the saved version will replace the
version created in .Rprofile. (Unless you start R using R --no-restore)

Hi Greg,
Thanks for your prompt reply. I have added 'library(utils)' in my
Rprofile file and now it is working fine.
Thanks and regards,

The .Rprofile file is processed before all the standard packages are
loaded, that is why you are seeing the error. If you instead run the
command as utils::read.csv or use library or require to manually load
the utils package before calling read.csv then everything should work
for you.

Hi again,
I am trying to build a procedure such that whenever R starts, it will
read some CSV file.
Therefore I put a code sometime like 'read.csv(...)' in my Rprofile
file. However if I put this function there then I am getting an error
saying 'Error: could not find function "read.csv"', wheneve

Are you sure the file is in your current working directory? Often people
simply put the full path such as "/Users/Name/RBS.csv"

Make sure you have the correct path to the file.

I am trying to read a csv file using the code;
contol <- read.csv("RBS.csv")
This is the error message I got;
Error in file(file, "r") : unable to open connection
In addition: Warning message:
In file(file, "r") :
cannot open file 'RBS.csv', reason 'No such file or directory'
Where was the mistak
When you read in a .csv file with some empty cells using read.csv,
there is no need to specify anything - empty cells will be recorded as
NAs automatically:
try:
data1<-read.csv("oa_2006.csv")

Hi,
I have a comma seperated data file which has blanks in it. I am trinying to

I want the missing values to be "NA". instead R reads them as "U". Any idea
why this happens ?

Just as an update on encoding (which may or may not be of interest). I
changed the read.csv command for three .csv files I was reading to specify
the encoding to be
encoding="CP1252"
and all 3 files were read in without problems on linux. Last night I
swapped the analysis back on to my windo

You don't. Either you know it, or you are up the proverbial creek (or

I have encountered a problem with reading a .csv file on a linux box. I
can read the file on my windows machine (under XP) but on the linux box it
gives :
