In NCmisc: Miscellaneous Functions for Creating Adaptive Functions and Scripts

Tidy display function for matrix objects

Description

This function prints the first and last columns and rows of a matrix, and more, if desired. Allows previewing of a matrix without overloading the console. Most useful when data has row and column names.

Usage

prv.large(
  largeMat,
  rows = 3,
  cols = 2,
  digits = 4,
  rL = "Row#",
  rlab = "rownames",
  clab = "colnames",
  rownums = T,
  ret = FALSE,
  warn = TRUE
)

Arguments

largeMat	a matrix
rows	number of rows to display
cols	number of columns to display
digits	number of digits to display for numeric data
rL	row label to describe the row names/numbers, e.g, row number, ID, etc
rlab	label to describe the data rows
clab	label to describe the data columns
rownums	logical, whether to display rownumbers or ignore them
ret	logical, whether to return the result as a formatted object, or just print to console
warn	logical, whether to warn if the object type is not supported

Examples

mat <- matrix(rnorm(1000),nrow=50)
rownames(mat) <- paste("ID",1:50,sep="")
colnames(mat) <- paste("Var",1:20,sep="")
prv.large(mat)
prv.large(mat,rows=9,cols=4,digits=1,rlab="samples",clab="variables",rownums=FALSE)
