xMLparameters
is supposed to visualise cross-validation
performance against tuning parameters.
xMLparameters(data, nD = c("auto", "1D", "2D", "3D"), contour = TRUE, main = "Repeated cross-validation", xlab = NA, ylab = NA, zlab = NA, clab = "AUC (repeated CV)", nlevels = 50, colormap = c("lightblue-lightyellow-darkorange-darkred", "bwr", "jet", "gbr", "wyr", "br", "yr", "rainbow", "wb"), highlight = TRUE, x.label.cex = 0.8, x.label.srt = 30, theta.3D = 40, phi.3D = 25)
data |
an object of the class "train" or "train.formula" (resulting from caret::train) used for 1D or 2D visualisation. Alternatively, it can be a data frame used for 2D or 3D visualisation |
nD |
an integer specifying the dimension of the visualisation. It can be one of '1D', '2D' and '3D' and 'auto' (if input data is a "train" object) |
contour |
logical to indicate whether coutour plot should be also included |
main |
a title for the plot |
xlab |
a title for the x axis |
ylab |
a title for the y axis |
zlab |
a title for the z axis |
clab |
a title for the colorbar |
nlevels |
the number of levels to partition the input matrix values. The same level has the same color mapped to |
colormap |
short name for the colormap. It can be one of "jet" (jet colormap), "bwr" (blue-white-red colormap), "gbr" (green-black-red colormap), "wyr" (white-yellow-red colormap), "br" (black-red colormap), "yr" (yellow-red colormap), "wb" (white-black colormap), and "rainbow" (rainbow colormap, that is, red-yellow-green-cyan-blue-magenta). Alternatively, any hyphen-separated HTML color names, e.g. "blue-black-yellow", "royalblue-white-sandybrown", "darkgreen-white-darkviolet". A list of standard color names can be found in http://html-color-codes.info/color-names |
highlight |
logical whether to highlight the point with the maximum value |
x.label.cex |
the x-axis label size |
x.label.srt |
the x-axis label angle (in degree from horizontal) |
theta.3D |
the azimuthal direction. By default, it is 40 |
phi.3D |
the colatitude direction. By default, it is 20 |
invisible
none
