matrix.trellis

0th

Percentile

Convert a one-dimensional trellis object to a two-dimensional trellis object. This permits combineLimits and useOuterStrips to work.

Keywords

Usage
matrix.trellis(x = NA, nrow = 1, ncol = 1, byrow = FALSE, dimnames = NULL)

# S3 method for trellis as.matrix(x, ..., row = FALSE, yname)

Arguments
x

x

nrow, ncol, byrow, dimnames

See matrix.

row

Logical. The default is FALSE to match the behavior of the generic as.matrix. I think TRUE usually looks better.

yname

Character. Provides the name of the generated conditioning factor.

Other arguments are ignored.

Details

matrix.trellis lets the user specify nrow and ncol. as.matrix.trellis produces either be a single column (by default) or a single row.

Value

trellis object with length(dim(x)) == 2 and specified nrow and ncol.
