gene_pad_arr: Pad array to fit a different shape

In DJFernandes/ABIgeneRMINC: Read, Write, and Analyzing Allen Gene Expression Raw Data

Pad array to fit a different shape

Description

Pad array to fit a different shape

Usage

gene_pad_arr(x, new.dims, side = c("left", "right", "both"), padval = 0)

Arguments

x	Array to pad
new.dims	new dimensions
side	should padding be applied to the left, right, or both (ties are broken by the left)?
padval	what value should be used for padding?

Value

array padded so it has dimensions of new.dims

Examples

# read a gene expression file
filename=system.file('extdata/Pdyn_P56_coronal_71717084_200um.zip',package="ABIgeneRMINC")
gene.expression=read.raw.gene(filename)

# make it into an array 
gene.expression.array=array(gene.expression,rev(attr(gene.expression,'sizes')))
# synonymous with mincArray(gene.expression))

# dimensions of array
dim(gene.expression.array)
# 67 41 58

# pad the array
padded.gene.expression.array = gene_pad_arr(gene.expression.array,new.dims=c(100,99,98),side='both')

# dimensions of padded array
dim(padded.gene.expression.array)
# 100 99 98
