plot1(x, jitter = FALSE, at = NULL, ...)
?axis
.par
This function creates a plot for a single vector of numerical values, arranging them horizontally from minimum to maximum.
This is a special type of (scatter)plot, with points being arranged only on the horizontal axis (it has no vertical axis). Useful when inspecting if points are grouped into naturally occuring clusters, mainly for crisp calibration purposes.
The argument ...
is used to pass various graphical parameters for the
various plotting functions used.
The points have a default cex
(character expansion) value of 1, and
a default pch
value of 1 (empty points), which can be modified
accordingly (for example with value 21 of filled points). When pch = 21
,
the color for the margins of the points can be specified via the argument
col
, while the argument bg
will determine the fill color
of the points.
The axis labels have a default cex.axis
value of 0.8, which affects
both the tickmarks labels and the axis labels.
When jittering the points, default values of 0.5 are used for the parameters
factor
and amount
, on the horizontal axis.
