generateWeights {manta} | R Documentation |
Because the manta plot uses integer count data, many of the points overlap and hide a large portion of the data. This function allows one to apply a weighting scheme to jitter points out from under each other both to show the density and expose the content of their pies (if applicable).
generateWeights(x, w.clmn, agg.clmn, cond.clmn, ct.clmns=NULL)
x |
an alignment dataframe |
w.clmn |
a string corresponding to a column with weight data |
agg.clmn |
a string corresponding to a column with an aggregation index. |
cond.clmn |
a string corresponding to a column with condition factor |
ct.clmns |
a string corresponding to a column with count data |
a 2 by n weight matrix
