Select genes according to the values of a few different statistics
maSelectGnames(statdata, crit1 = 50, crit2 = crit1, sub = TRUE, selectstat, operate = c("intersect", "union"))statdata |
A numerical matrix where the rows corresponds to genes and the columns corresponds to various statistics corresponding to a particular gene. |
crit1 |
The number of points to be selected. If crit1 < 1, the crit1*100% spots with the smallest M values will be selected. If crit1 >= 1, the crit spots with the smallest M values are selected. |
crit2 |
Similar to "crit1". If crit2 < 1, the crit2*100% spots with the largest M values will be selected. If crit2 >= 1, the crit2 spots with the largest M values are selected. |
sub |
A "logical" or "numeric" vector indicating the subset of genes to be consider. |
selectstat |
A integer value indicating the statistics where the final ranking is based on. |
operate |
The operation used to combined different rankings |
This functions calls stat.gnames to select say the 100
most extreme genes from various statistics and combined the different
gene lists by either union or intersection.
A vector of numeric values.
