Dear all;

Thanks. Here are the dput results as Duncan suggested.

Regards,

Hi all;

I have data at 734*22 dimensions with rows and columns names are
non-numeric.When I convert this data into matrix then all values show up
with quotes. Then when I use
x1= noquotes(x) to remove the quotes from the matrix then non-numeric

row

names remain all other values in matrix disappear.

Your help is greatly appreciated.

Matrices in R can have only one type.  If you start with a dataframe and
any columns contain character data, all entries will be converted to
character, and the matrix will be displayed with quotes.

When you say all values disappear, it sounds as though you are displaying
strings containing nothing (or just blanks).  Those will be displayed as

""

normally, but if the matrix is marked to display without quotes, they are
displayed as empty strings, so it will appear that nothing is displayed.

You can see the structure of the original data using the str() function,
e.g. str(x) should display types for each column.

If this isn't enough to explain what's going on, please show us more
detail.  For example, show us the result of

y <- x[1:5, 1:5]
dput(y)

both before and after converting x to a matrix.
