Loadings scatter plot
Witryna1 cze 2024 · A visual approach to selecting the number of principal components to keep means the use of a scree plot. A scree plot shows the number of components on the X-axis against the proportion of the variance explained on the Y-axis. The suggested number of components to keep is where the plot forms an elbow and the curve … Witryna6 lis 2024 · For convenience, the score plot (scatter plot) and the loadings plot (vector plot) are shown below for the iris data. Notice that the loadings plot has a much smaller scale than the score plot. If you overlay these plots, the vectors would appear relatively small unless you rescale one or both plots.

WitrynaIf we want to move them along x axis only in the case that they are overlapping with text, use move_only= {'points':'y', 'text':'xy'}. Also in the beginning the function chooses optimal alignment of texts relative to their original points, so we only want that to happen along the y axis too, hence autoalign='y'.
WitrynaIf a scatter plot is produced (i.e., scoreplot, corrplot, or loadingplot with scatter = TRUE ), the labels are used instead of plot symbols for the points plotted.
