print.char.matrix {Hmisc} | R Documentation

## Function to print a matrix with stacked cells

### Description

Prints a dataframe or matrix in stacked cells. Line break charcters in a matrix element will result in a line break in that cell, but tab characters are not supported.

### Usage

    print.char.matrix(x, file = "", col.name.align = "cen", col.txt.align = "right",
        cell.align = "cen", hsep = "|", vsep = "-", csep = "+", row.names = TRUE,
        col.names = FALSE, append = FALSE,
        top.border = TRUE, left.border = TRUE, ...)

### Arguments

`x` | a matrix or dataframe
`file` | name of file if file output is desired. If left empty, output will be to the screen
`col.name.align` | if column names are used, they can be aligned right, left or centre. Default `"cen"` results in names centred between the sides of the columns they name. If the width of the text in the columns is less than the width of the name, `col.name.align` will have no effect. Other options are `"right"` and `"left"`.
`col.txt.align` | how character columns are aligned. Options are the same as for `col.name.align` with no effect when the width of the column is greater than its name.
`cell.align` | how numbers are displayed in columns
`hsep` | character string to use as horizontal separator, i.e. what separates columns
`vsep` | character string to use as vertical separator, i.e. what separates rows. Length cannot be more than one.
`csep` | character string to use where vertical and horizontal separators cross. If `hsep` is more than one character, `csep` will need to be the same length. There is no provision for multiple vertical separators
`row.names` | logical: are we printing the names of the rows?
`col.names` | logical: are we printing the names of the columns?
`append` | logical: if {file} is not `""`, are we appending to the file or overwriting?
`top.border` | logical: do we want a border along the top above the columns?
`left.border` | logical: do we want a border along the left of the first column?
`...` | unused

### Details

If any column of `x` is a mixture of character and numeric, the distinction between character and numeric columns will be lost. This is especially so if the matrix is of a form where you would not want to print the column names, the column information being in the rows at the beginning of the matrix.

Row names, if not specified in the making of the matrix will simply be numbers. To prevent printing them, set `row.names = FALSE`.

### Value

No value is returned. The matrix or dataframe will be printed to file or to the screen.

### Examples

    data(HairEyeColor)
    print.char.matrix(HairEyeColor[ , , "Male"], col.names = TRUE)
    print.char.matrix(HairEyeColor[ , , "Female"], col.txt.align = "left", col.names = TRUE)

    z <- rbind(c("", "N", "y"),
               c("[ 1.34,40.3)\n[40.30,48.5)\n[48.49,58.4)\n[58.44,87.8]",
                 " 50\n 50\n 50\n 50",
                 "0.530\n0.489\n0.514\n0.507"),
               c("female\nmale", " 94\n106", "0.552\n0.473"  ),
               c("", "200", "0.510"))
    dimnames(z) <- list(c("", "age", "sex", "Overall"),NULL)

    print.char.matrix(z)
