Decimal alignment

Source: R/tostring.R
decimal_align.Rd

Aligning decimal values of string matrix. Allowed alignments are: dec_left, dec_right, and decimal.

Usage 

decimal_align(string_mat, align_mat)

Arguments

string_mat

(character matrix)
"string" matrix component of MatrixPrintForm object.

align_mat

(character matrix)
"aligns" matrix component of MatrixPrintForm object. Should contain either dec_left, dec_right, or decimal for values to be decimal aligned.

Value

A processed string matrix of class MatrixPrintForm with decimal-aligned values.

Details

Left and right decimal alignment (dec_left and dec_right) differ from center decimal alignment (decimal) only when there is padding present. This may occur if column widths are set wider via parameters widths in toString or colwidths in paginate_*. More commonly, it also occurs when column names are wider. Cell wrapping is not supported when decimal alignment is used.

Examples 

dfmf <- basic_matrix_form(mtcars[1:5, ])
aligns <- mf_aligns(dfmf)
aligns[, -c(1)] <- "dec_left"
decimal_align(mf_strings(dfmf), aligns)
