run.cor.examp | R Documentation |
Make a scatterplot and a Tk slider window that allows you to interactively set the correlation and/or R^2.
run.cor.examp(n=100, seed, vscale=1.5, hscale=1.5, wait=FALSE)
run.cor2.examp(n=100, seed, vscale=1.5, hscale=1.5, wait=FALSE)
run.old.cor.examp(n = 100, seed)
run.old.cor2.examp(n = 100, seed)
n |
Number of points to plot. |
seed |
What seed to use. |
vscale |
Vertical scale passed to tkrplot. |
hscale |
Horizontal scale passed to tkrplot. |
wait |
Should R wait for the tk window to close. |
The function run.cor.examp
draws a scatterplot and allows you
to set the correlation using a Tk slider window.
The function run.cor2.examp
does the same, but has a slider for
R^2 as well as the correlation, when either slider is moved the other
one will update to match.
The 2 "old" versions use the default graphics device with a seperate window with the sliders, the versions without "old" in the name include the plot and sliders together in a single tk window.
The size of the plot can be changed by changing the values in the hscale and vscale boxes and clicking on the "Refresh" button.
If wait
is TRUE, then the return value is a list with the x and
y values of the final plot.
If wait
is FALSE (and in the "old" versions) an invisible NULL
is returned.
If wait
is TRUE then R will wait until you click on the
"Exit" button before you can use your R session again. If wait
is FALSE then the tk window will appear, but R will regain control so
that you can continue to use R as well as interact with the
demonstration window.
