to make things easier for you you could do
x111 <-read.table( file.choose(), ... )
Also: Why are you setting sep="" ? Your filename suggests
Or, you should put the whole path to that file, for example
file='C:/My documents/x111.csv'

1) You need to use sep="," which is appropriate for a CSV file.
2) You need to specify the FULL path to the file. See
http://cran.r-project.org/bin/windows/base/rw-FAQ.html#R-can_0027t-find-my-file
3) You can use read.csv which is the read.table variant for CSV files.
For example
a <- read.

You're probably righ
select the directory with setwd() and then import data:
setwd("d:/.../yourdirectory")
x111 <- read.table("x111.csv",...)
or indicate path behind filename:
x111 <- read.table("d:/.../yourdirectory/x111.csv",...)
besides, there are other functions to import data.
see ?read.table

getwd() gives you the working directory in which the datafile has to
reside.

Hello,
I am a very new user of R. I've spent several hours trying to import
data, so I feel okay asking the list for help. I had an Excel file,
then I turned it into a "csv" file, as instructed by directions. My
filename is "x111.csv." I then used the following commands to read this

maybe you can use the array function,like
>array(CO2,dim(CO2),list(rownames(CO2),colnames(CO2)))
and matrix is just a specif type of array,so maybe you can use as.matrix
>as.matrix(CO2)
the above tow,the CO2 is a data.frame which can use read.table to read in.
the third way is:use the scan the re
Please consult the `R Data Import/Export Manual'. You could be using
scan(), as in
matrix(scan("some_file", 0), nrow=n, byrow=TRUE)

Did some search but couldn't find useful result.
I am trying to read a n*m dimension data with read.table, what i need is a
numeric array,
is there any efficient way to allow me get this array directly instead of a
list?
I tried to use as.array() to change the mode, but seems it doesn't work
