| spreadout {PairViz} | R Documentation |
Functions to prepare for categorical parallel coordinates, drawn by catpcp.
Description
factor_spreadout spreads out the data at each factor level. rater_spreadout spreads out the data at each rating level. The rater version is appropriate when the variables (factors) have all the same levels.
Usage
factor_spreadout(d)
rater_spreadout(d, levs, minspace = NULL,scale=FALSE)
Arguments
d |
A data frame where each variable can be interpreted as a factor. |
levs |
The rating levels. Specifying this controls the order of rating levels on each axis. |
minspace |
The minimum amount of space between the bars. |
scale |
If scale=FALSE, the ith rater values are spreadout about the value i. If scale=TRUE, all values are scaled to 0-1. |
Details
factor_spreadout spreads out the data at each factor level. It returns a list with two components. The first is data, containing the spreadout data, scaled to 0-1. The second is bars, which is a list whose ith component gives the bottom and top of the bars for the ith variable of d.
rater_spreadout spreads out the data at each rater level. It returns a list with two components. The first is data, containing the spreadout data. If scale=FALSE, the ith rater values are spreadout about the value i. If scale=TRUE, all values are scaled to 0-1. The second component is bars, which is a list whose ith component gives the bottom and top of the bars for the ith variable of d.
