replaceTabs.inner: Display text information in a graphics plot.

Description

This function displays text output in a graphics window. It is the equivalent of 'print' except that the output is displayed as a plot.

Usage

replaceTabs.inner(text, width = 8)
replaceTabs(text, width = 8)

Arguments

text

in the function 'replaceTabs', the text string to be processed

width

in the function 'replaceTabs', the number of spaces to replace tabs with

object

Object to be displayed.

halign

Alignment in the x direction, one of "center", "left", or "right".

valign

Alignment in the y direction, one of "center", "top" , or "bottom"

cex

Character size, see par for details. If unset, the code will attempt to use the largest value which allows the entire object to be displayed.

max.cex

Sets the largest text size as a ceiling

rmar,cmar

Space between rows or columns, in fractions of the size of the letter 'M'.

show.rownames,show.colnames

Logical value indicating whether row or column names will be displayed.

hadj,vadj

Vertical and horizontal location of elements within matrix cells. These have the same meaning as the adj graphics paramter (see par).

row.valign

Sets the vertical alignment of the row as "top", "bottom", or (default) "center".

heading.valign

Sets the vertical alignment of the heading as "top", (default) "bottom", or "center".

mar

Figure margins, see the documentation for par.

col.data

Colors for data elements. If a single value is provided, all data elements will be the same color. If a matrix matching the dimensions of the data is provided, each data element will receive the specified color.

col.rownames,col.colnames

Colors for row names and column names, respectively. Either may be specified as a scalar or a vector of appropriate length.

wrap

If TRUE (default), will wrap column names and rownames

wrap.colnames

The number of characters after which column labels will be wrapped. Default is 10.

wrap.rownames

The number of characters after which row headings will be wrapped. Default is 10.

fixed.width

default is TRUE

cspace

default is 1

lspace

default is 1

tab.width

default is 8

...

Optional arguments passed to the text plotting command or specialized object methods

Details

A new plot is created and the object is displayed using the largest font that will fit on in the plotting region. The halign and valign parameters can be used to control the location of the string within the plotting region.

For matrixes and vectors a specialized textplot function is available, which plots each of the cells individually, with column widths set according to the sizes of the column elements. If present, row and column labels will be displayed in a bold font.

textplot also uses replaceTabs, a function to replace all tabs in a string with an appropriate number of spaces. That function was also written by Gregory R. Warnes and included in the 'gplots' package.

Examples

# Also see the examples in the original gplots textplot function
data(managers)
textplot(table.AnnualizedReturns(managers[,1:6]))

# This was really nice before Hmisc messed up 'format' from R-base
# prettify with format.df in hmisc package
# require("Hmisc")
# result = t(table.CalendarReturns(managers[,1:8]))[-1:-12,]

#  textplot(Hmisc::format.df(result, na.blank=TRUE, numeric.dollar=FALSE,
#           cdec=rep(1,dim(result)[2])), rmar = 0.8, cmar = 1,  max.cex=.9,
#           halign = "center", valign = "top", row.valign="center", wrap.rownames=20,
#           wrap.colnames=10, col.rownames=c("red", rep("darkgray",5),
#           rep("orange",2)), mar = c(0,0,4,0)+0.1)
