In IdMappingAnalysis: ID Mapping Analysis

Description Usage Arguments Value Author(s) See Also Examples

Compute log10 of a numerical vector combined with thresholding on minimum value.

## Static method (use this):
## DataFilter$logTen(x, filtParams, ...)

## Don't use the below:
## S3 method for class 'DataFilter'
logTen(static, x, filtParams, ...)

`x`	`numeric` input `vector`.
`filtParams`	`vector` of constraint parameters. If a particular output element is less or equal than filtParams[1] it is assigned the filtParams[2] value.
`...`	Not used

clipped log10 of an input numeric vector.

 #compute log10 transform of mrna experiment data replacing (clipping)
 #the output values with log10(0.5)for input values < 0.5
 fltExperimentSet<-DataFilter$do.apply(examples$mrnaExperimentSet,

 #print the number of elements clipped
 sum(fltExperimentSet[,-1]==log10(0.5))-sum(examples$mrnaExperimentSet[,-1]<=0.5);
