Easy integration of (small) tables into (error) messages

print_and_capture.rd

Some (error) messages are more understandable if small (frequency) tables are used for clearness. The function simplifies integration of these tables. The function is intended to be used in combination with message, stop, or cat, for example.

Usage

print_and_capture (x, spaces = 0)

Arguments

x

The object which should be integrated. Normally, a (small) table or data frame.

spaces

Number of spaces between left border and the table

Value

a string which may be combined with messages

Examples

frequency.table <- as.table(matrix(c(12,0,5,7),2,2))
attr(frequency.table, "dimnames") <- list("sex" = c("male", "female"),
        "migration" = c(TRUE, FALSE))
message("Some combinations of variables with zero observations: \n",
        print_and_capture(frequency.table, spaces = 5))
#> Some combinations of variables with zero observations: 
#>               migration
#>       sex      TRUE FALSE
#>         male     12     5
#>         female    0     7
