R: Enhanced Dot Chart for LaTeX Picture Environment with epic

latexDotchart {Hmisc} | R Documentation

## Enhanced Dot Chart for LaTeX Picture Environment with epic

### Description

`latexDotchart` is a translation of the `dotchart3` function for producing a vector of character strings containing LaTeX picture environment markup that mimics `dotchart3` output. The LaTeX `epic` and `color` packages are required. The `add` and `horizontal=FALSE` options are not available for `latexDotchart`, however.

### Usage

    latexDotchart(data, labels, groups=NULL, gdata=NA,
      xlab='', auxdata, auxgdata=NULL, auxtitle,
      w=4, h=4, margin,
      lines=TRUE, dotsize = .075, size='small', size.labels='small',
      size.group.labels='normalsize', ttlabels=FALSE, sort.=TRUE,
      xaxis=TRUE, lcolor='gray', ...)

### Arguments

`data` | a numeric vector whose values are shown on the x-axis
`labels` | a vector of labels for each point, corresponding to `x`. If omitted, `names(data)` are used, and if there are no `names`, integers prefixed by `"#"` are used.
`groups` | an optional categorical variable indicating how `data` values are grouped
`gdata` | data values for groups, typically summaries such as group medians
`xlab` | x-axis title
`auxdata` | a vector of auxiliary data, of the same length as the first (`data`) argument. If present, this vector of values will be printed outside the right margin of the dot chart. Usually `auxdata` represents cell sizes.
`auxgdata` | similar to `auxdata` but corresponding to the `gdata` argument. These usually represent overall sample sizes for each group of lines.
`auxtitle` | if `auxdata` is given, `auxtitle` specifies a column heading for the extra printed data in the chart, e.g., `"N"`
`w` | width of picture in inches
`h` | height of picture in inches
`margin` | a 4-vector representing, in inches, the margin to the left of the x-axis, below the y-axis, to the right of the x-axis, and above the y-axis. By default these are computed making educated cases about how to accommodate `auxdata` etc.
`lines` | set to `FALSE` to suppress drawing of reference lines
`dotsize` | diameter of filled circles, in inches, for drawing dots
`size` | size of text in picture. This and the next two arguments are LaTeX font commands without the opening backslash, e.g., `'normalsize'`, `'small'`, `'large'`, `smaller[2]`.
`size.labels` | size of labels
`size.group.labels` | size of labels corresponding to `groups`
`ttlabels` | set to `TRUE` to use typewriter monospaced font for labels
`sort.` | set to `FALSE` to keep `latexDotchart` from sorting the input data, i.e., it will assume that the data are already properly arranged. This is especially useful when you are using `gdata` and `groups` and you want to control the order that groups appear on the chart (from top to bottom).
`xaxis` | set to `FALSE` to suppress drawing x-axis
`lcolor` | color for horizontal reference lines. Default is `"gray"`
`...` | ignored

    y1 <- runif(26)
    y2 <- pmax(0, y1 - runif(26, 0, .1))
    z <- latexDotchart(y1, g, groups=maj, auxdata=n, auxtitle='n', xlab='Y',
