MRIaggr (version 1.1.5)

calcTableLesion: Vertical distribution of the lesion

Description

Compute the number of lesion observations at each slice.

Usage

"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")
