Imports non-rejection rates from an external flat file.
name of the flat file with the data on the non-rejection rates.
number of tests performed in the estimation of these non-rejection rates.
This function expects a flat file with three tab-separated columns corresponding to, respectively, 0-based index of one of the variables, 0-based index of the other variable, number of non-rejected tests for the pair of variables of that row in the text file. An example of a few lines of that file would be:
1 2 3 4 5
6 3 95 6 4 98 6 5 23 7 0 94 7 1 94
After reading the file the function builds a matrix of non-rejection rates by
dividing the number of non-rejected tests by
nTests. Note that if the flat
file to be imported would eventually have directly the rates instead of the
number of tests, these can be also imported by setting
This function is thought to be used to read files obtained from the standalone
parallel version of
qpNrr which can be downloaded from
