MRIaggr-calcTableLesion: Vertical distribution of the lesion

In bozenne/MRIaggr: Management, Display, and Processing of Medical Imaging Data

Description

Compute the number of lesion observations at each slice.

Usage

## S4 method for signature 'MRIaggr'
calcTableLesion(object, maskN, mask = NULL, numeric2logical = FALSE,
         verbose = optionsMRIaggr("verbose"), update.object = FALSE, overwrite = FALSE)

Arguments

object	an object of class MRIaggr. REQUIRED.
maskN	the binary contrast parameter indicating the lesion. character. REQUIRED.
mask	the binary contrast parameter indicating the brain. character or NULL if no mask is available.
numeric2logical	should mask and maskN values be converted to logical ? logical.
verbose	should the execution of the function be traced ? logical.
update.object	should the resulting lesion table be stored in object ? logical.
overwrite	if a lesion table is already stored in object@table_lesion, can it be overwritten ? logical.

Value

A data.frame containing the number of observation within the mask at each slice.

Examples

## load a MRIaggr object
data("MRIaggr.Pat1_red", package = "MRIaggr")

## compute table
res <- calcTableLesion(MRIaggr.Pat1_red, maskN = c("MASK_DWI_t0", "MASK_T2_FLAIR_t2"),
     numeric2logical = TRUE, update.object = TRUE, overwrite = TRUE)

## extract table
res <- selectTable(MRIaggr.Pat1_red, "lesion")
