gen_icrfnames {lazy.irt}

R Documentation

Generate the Row Names of vec(icrf) as the Combination of Theta Values and Category Names.

Description

Generate the Row Names of vec(icrf) as the Combination of Theta Values and Category Names.

Usage

gen_icrfnames(
  theta,
  ncat,
  zero = 0,
  cat.first = 0,
  digits = 2,
  catroot = "c",
  sep = ":",
  compress = 0
)

Arguments

theta	Numeric vector of theta values.
ncat	# of categories
zero	= 1 to include the 0-th category
cat.first	= 1 to chage the category fist. = 2 to change the category first and place category name before theta. This is for vec(icrf, byrow=1 ).
digits	# of digits after the decimal point of theta.
catroot	The root character for category.
sep	The caracter separating theta and category.
compress	= 1 to remove all the blanks in the result

Details

This function creates a character vector consisting of
c( thetavalue1:catvalue1, thetavalue2:catvalue1, ... ) .
If cat.first=1, the result is
c( thetavalue1:catvalue1, thetavalue1:catvalue2, ... ) ,
and if cat.first=2,
c( catvalue1:thetavalue1, catvalue2:thetavalue1, ... ) ,

Value

A vector consisting of rownames of vec(icrf) or vec(icrf, byrow=1).

Examples

gen_icrfnames(seq(-4,4,length=7), 3 )
gen_icrfnames(seq(-4,4,length=7), 3, cat.first=1 )
