filter_exons: Filter Exons with Zero Variance
In JMoon1/v2e: Assemble Comparative AS Datasets

Description Usage Arguments Examples

Removes exons without evidence of alternative splicing

1	filter_exons(data, sp, indivs, stringent = FALSE)

data

The PSI file to be filtered sp The total number of columns containing exon names indivs A numerical vector containing the number of individuals for each tissue, in order from left to right stringent Applies a stronger filter to return exons w/ at least 2 individuals per tissue/species (Required for EVE model). Defaults to FALSE.

filter_exons(data = PSI_brain, sp = 3, indivs = c(6,6,3), stringent = TRUE) -> PSI_brain

# don't forget to subset the complementary varPSI file to match
varPSI_brain = varPSI_brain[varPSI_brain$V1 %in% PSI_brain$V1, ]
