dimnames.lpExtPtr function

Dimnames of an Object

Retrieve or set the dimnames in an lpSolve linear program model object.

## S3 method for class 'lpExtPtr'
dimnames(x)
## S3 replacement method for class 'lpExtPtr'
dimnames(x) <- value

Arguments

• x: an lpSolve linear program model object.
• value: a list containing two character vectors of lengths m and n specifying the row names and the column names for the lpSolve linear program model object. The number of constraints in x is denoted by m and the number of decision variables by n.

Returns

a list of two character vectors containing the row names and the column names in the lpSolve linear program model object.

Examples

lps.model <- make.lp(4, 0)

x <- c(6,2,4,9)
add.column(lps.model, x)

y <- c(3,1,5)
ind <- c(1,2,4)
add.column(lps.model, y, ind)

dimnames(lps.model) <- list(c("alpha", "bravo", "charlie", "delta"),
                     c("whiskey", "tango"))
