[R] Importing all observations and variables from csv file into dataframe

[R. Michael Weylandt]

You aren't reading the file in at all: notice that,

> summary("MooGoesTheCow",header=TRUE,as.is=TRUE)
   Length     Class      Mode
        1 character character

This is because you are asking for a summary of the string containing
the file name, not the file itself.

Rather, use

X = read.csv("C:\\Documents\\R_dfiles\\H_N_T.csv",header=TRUE,as.is=TRUE)

and then start looking at X which will be an R object (data frame most
likely) storing all the values of the spreadsheet.

Hope this helps,

Michael

Does that happen when you save a an Excel file in .csv format?  I have used the function file.choose() to pull in the file into R.  When I use the summary command I get:

Is there a way to clear the one-cell selection status?  Or perhaps there is another issue that needs addressing.  I would like to get this data table configured into R as a dataframe.
