F_2_panel.qqmathline {lattice} | R Documentation |
Useful panel function with qqmath. Draws a line passing through the points (usually) determined by the .25 and .75 quantiles of the sample and the theoretical distribution.
panel.qqmathline(x, y = x, distribution = qnorm, probs = c(0.25, 0.75), qtype = 7, groups = NULL, ..., identifier = "qqmathline")
x |
The original sample, possibly reduced to a fewer number of
quantiles, as determined by the |
y |
an alias for |
distribution |
quantile function for reference theoretical distribution. |
probs |
numeric vector of length two, representing probabilities. Corresponding quantile pairs define the line drawn. |
qtype |
the |
groups |
optional grouping variable. If non-null, a line will be drawn for each group. |

other arguments. |
identifier |
A character string that is prepended to the names of grobs that are created by this panel function. |
