Calculates mean ranks where some ranks may be missing
1 |
x |
A matrix of ranks that may contain ties and NAs. Objects ranked are assumed to be columns and ranking methods rows. |
allranks |
An optional list of all ranks that might have been made. |
labels |
Optional labels for the ranks. |
rankx |
Whether to convert competition ranks, or any other set of numeric values, into the usual mean rankings for ties. |
meanranks calls muranks to complete the rank matrix before calculating the mean ranks for each column if there are any NAs in x.
Note that cats2ranks interprets each value in x as a nominal level variable and its index as the rank, while meanranks interprets values as ordinal level (ranks). Thus if a matrix or data frame of category labels is passed to meanranks, it will not give the correct mean ranks.
A list with the following components:
ranks |
x with any NAs replaced by the mean of unallocated ranks for each row. |
labels |
The vector of labels, defaulting to the integers 1:allranks. |
mean.ranks |
A vector of mean ranks for each value of allranks. |
