plot.represampling
displays the partitions or samples corresponding
arising from the resampling of a data set.
# S3 method for represampling plot(x, data, coords = c("x", "y"), pch = "+", wiggle_sd = 0, ...) # S3 method for resampling plot(x, ...)
x | a represampling resp. resampling object. |
---|---|
data | a |
coords | vector of length 2 defining the variables in |
pch | point symbol (to be passed to points). |
wiggle_sd | 'wiggle' the point locations in x and y direction to avoid overplotting of samples drawn multiple times by bootstrap methods; this is a standard deviation (in the units of the x/y coordinates) of a normal distribution and defaults to 0 (no wiggling). |
... | additional arguments to plot. |
This function is not intended for samples obtained by resampling with replacement (e.g., bootstrap) because training and test points will be overplotted in that case. The size of the plotting region will also limit the number of maps that can be displayed at once, i.e., the number of rows (repetitions) and fields (columns).
