uwmw_Extract: Extract data from uwmwRes and uwmwEstimate objects.

In CenterForStatistics-UGent/unifiedWMWqPCR: Unified Wilcoxon-Mann Whitney Test for testing differential expression in qPCR data

Extract data from uwmwRes and uwmwEstimate objects.

Description

For both uwmwRes and uwmwEstimate objects, you can use the square bracket operators to extract information much like you would do for a matrix.

Usage

## S4 method for signature 'uwmwRes,character'
x[i, j, drop = TRUE]

## S4 method for signature 'uwmwEstimate,character'
x[i, j, drop = TRUE]

## S4 method for signature 'uwmwRes,ANY'
x[i, j, drop = TRUE]

## S4 method for signature 'uwmwEstimate,ANY'
x[i, j, drop = TRUE]

Arguments

x	a uwmwRes object
i	numeric or character vector
j	optional numeric or character vector
drop	logical value. If set to FALSE and the result of the extraction is a single row or column, dimensions are dropped. Defaults to TRUE.

Details

The features can be extracted using the row index, and the estimates as

Value

mostly a matrix, unless drop=TRUE and a single row or column is selected. Then a vector.

Examples

# With an uwmwRes object
data(NBmat)
NBtest <- uWMW(NBmat,NBgroups)
# These two lines are the same
NBtest["hsa-mir-1"]
NBtest["hsa-mir-1", ]
# These two not
str(NBtest["hsa-mir-1",,drop=FALSE])
str(NBtest["hsa-mir-1",])
# These two give the same data, but in a different way:
se(NBtest) # unnamed
NBtest[,"se"] #

# With an uwmwEstimate object
NBodds <- getEstimate(NBtest,"odds")
gnames <- grep("let",names(NBodds),value=TRUE)
NBodds[gnames]
NBodds[gnames,c("ll","ul")]
