generate_y: Generate simulated nifti data examples

In seonjoo/neurorct: Neuroimaging basic functions used in LeeLab

Description

Generate simulated nifti data examples

Usage

generate_y(npergroup = 10, type = c("xs", "long"), saveinfti = FALSE,
  outfile = "")

Arguments

npergroup	sample size in each of the two groups. There are 2*n rows in the simulated data.
type	specify study type. 'xs': Cross-sectional; 'long':longitudinal.
saveinfti	if saveinfti = TRUE, save result to NIfTI file.
outfile	the name or connection of the file where the NIfTI file is saved to.

Value

if cross-sectional, an array of dim c(64, 64, 32, 2*npergroup); if longitudinal, a list of 2 such arrays for basline and follow-up.

Examples

library(neurorct)
# cross-sectional data
xs_data = generate_y(35, type = 'xs')

# longitudinal data
long_data = generate_y(20, type = 'long')
bl = long_data$baseline
fu = long_data$follow_up
