This is an internal function.
meanByClassHelper2(dtsources, tablenames, variables, invalidrecorder)
dtsources |
a list of opal object(s) obtained after
login in to opal servers; these objects hold also the
data assign to R, as |
tablenames |
a character vector, the name of the subset tables |

This function is called by the function 'ds.meanByClass' to produce the final table if the user sets the parmater 'type' to combine (the default behaviour of 'ds.meanByClass')
a matrix, a table which contains the length, mean and standard deviation of each of the specified 'variables' in each subset table.
