# datatable.rowmean()¶

For each row, find the mean values among the columns from cols skipping missing values. If a row contains only the missing values, this function will produce a missing value too.

## Parameters¶

cols

return

f-expression consisting of one column that has the same number of rows as in cols. The column stype is float32 when all the cols are float32, and float64 in all the other cases.

except

The exception is raised when cols has non-numeric columns.
