Columnwise Percentage

Description

Calculate the percentage (value divided by sum of values in the column) for each column

Usage

columnwisePercentage(x, default = 0, digits = 1)

Arguments

x	two dimensional numeric data structure
default	default value to be used if the calculated percentage is NA.
digits	number of digits (default: 1) to which the resulting percentages are to be rounded. Set to NA to suppress rounding

Examples

# Create a random matrix of integer values
M1 <- matrix(sample(100, 12), nrow = 4, dimnames = list(LETTERS[1:4], 1:3))

# Introduce some NA
values <- as.numeric(M1)
values[sample(length(values), 3)] <- NA
M2 <- matrix(values, nrow = nrow(M1), dimnames = dimnames(M1))

M1
columnwisePercentage(M1)

M2
columnwisePercentage(M2)
columnwisePercentage(M2, default = 0)
