[R] T-mode PCA

Hi, We are trying to classify atmospheric patterns using PCA and kmeans. In T-mode, the (non-normalized) loadings of the PCs are used as input variables for the k-means classification. As first step we perform PCA using "princomp" but the computed loadings produced by princomp are normalized

[R] Blank certain areas of a contour plot

Hi, I'm interpolating a list of syncronous accumulated precipitation observations collected over a number of raingauge stations sited over land, over a regular lat/lon grid using akima's interp(). Then, I plot and locate geographycally the resulting field with a filled.contour() and a call t

[R] "Rotated Lat-Lon" projection in mapproj

Hi, I'm trying to plot a field obtained from the atmospheric model WRF-NMM which uses a "Rotated Lat-Lon¨ map projection. The WRF documentation mentions that: · Rotates the earth's lat/lon grid such that the intersection of the equator and prime meridian is at the center of the model domain.
