R help - Aug 2012 - Basic question -loading data

Hi all,

New user here - I include the following command in the prompt

read.csv("document.csv", header = TRUE )

and the output shows up. 

But when I include the following command 

summary(data)

I get the following message "Error in object[[i]] : object of type
'closure' is not subsettable"

Can someone please advise why R is not reading my data?

Thanks

"data" is the name of a base function in R. Functions are objects of
type "closure". You can find out more about this function by reading
the help. If you create your own object named "data" then your object
will "hide" the base function and you won't be able to use it when
you want to. Type

?data

You used the read.csv function alright, but you did not assign the function
return value to a variable, so it just printed it and threw it away.

Try

dta <- read.csv("document.csv", header = TRUE )
str(dta)
summary(dta)

If you don't know whether some variable name you want to use is already
"taken", you can just type the name alone at the R prompt:

data

if it gives a not-found error then you should be safe to use it.  A couple of
tempting names you should also avoid are

c (commonly used function for making vectors. Tempting because it comes after
"a" and "b")
t (the transpose function for matrices. Tempting for naming time variables.)
df (density of the f distribution. Tempting because data frames are very often
used object classes.)

Hi Jeff,

Thank you - your comment was much appreciated.

I'm now running an ordered probit regression and get the following error:

Error in family$linkfun(mustart) : Value 1.125 out of range (0, 1)

I can't decipher (after looking at other posts on google!) why this error
occurs - is it something wrong with my dataset?

If anyone can advise that would be very helpful.

Thanks,
Dinuk

John/Michael, thanks for your comments.

I get the following error when I run my code (the code is attached as is a
section of the data set):
Error in family$linkfun(mustart) : Value 1.125 out of range (0, 1)

If anyone can please provide assistance that would be much appreciated - I'm
not sure if it's something wrong with my dataset or a bug in the program
"list"

Many thanks,
Dinuk
