| error.dots {psych} | R Documentation |
Yet one more of the graphical ways of showing data with error bars for different groups.
A dot.chart with error bars for different groups or variables is found using from describe, describeBy, or statsBy.
error.dots(x, var = NULL, se = NULL, group = NULL, sd = FALSE, head = 12, tail = 12,
sort = TRUE, decreasing = TRUE, main = NULL, alpha = 0.05, eyes = FALSE, min.n = NULL,
max.labels = 40, labels = NULL, groups = NULL, gdata = NULL, cex = par("cex"),
pt.cex = cex, pch = 21, gpch = 21, bg = par("bg"), color = par("fg"),
gcolor = par("fg"), lcolor = "gray", xlab = NULL, ylab = NULL, xlim = NULL, ...)
x |
A data frame or matrix of raw data, or the resulting object from |
var |
The variable to show |
se |
Source of a standard error |
group |
A grouping variable, if desired. Not implemented. |
sd |
if FALSE, confidence intervals in terms of standard errors, otherwise draw one standard deviation |
head |
The number of largest values to report |
tail |
The number of smallest values to report |
sort |
Sort the groups/variables by value |
decreasing |
Should they be sorted in increasing or decreasing order (from top to bottom) |
main |
The caption for the figure |
alpha |
p value for confidence intervals |
eyes |
Draw catseyes for error limits |
min.n |
If using describeBy or statsBy, what should be the minimum sample size to draw |
max.labels |
Length of labels (truncate after this value) |
labels |
Specify the labels versus find them from the row names |
groups |
ignored |
gdata |
ignored |
cex |
The standard meaning of cex for graphics |
pt.cex |
ignored |
pch |
Plot character |
gpch |
ignored |
bg |
background color |
color |
Color |
gcolor |
ignored |
lcolor |
ignored? |
xlab |
Label the x axis, if NULL, the variable name is used |
ylab |
If NULL, then the group rownames are used |
xlim |
If NULL, then calculated to show nice values |
... |
And any other graphic parameters we have forgotten |
Adapted from the dot.chart function to include error bars and to use the output ofdescribe, describeBy, and statsBy
To speed up multiple plots, the function can work from the output of a previous run. Thus describeBy will be done and the results can be show for multiple variables
Returns (invisibily) either a describeBy or describe object
