If main
is undefined the name of the matrix object supplied to the function is displayed, together with the value of crit
. On the line below the name of the data matrix from which the PCA was derived is displayed. However, if an alternate plot title is preferred it may be defined, e.g., main = "Plot Title Text"
. If no plot title is required set main = " "
.
If the variable names are longer than three characters the display can easily become cluttered. In which case the user should redefine the variable names in the input matrix from which the PCA was derived using the dimnames(matrix.name)[[2]]
construct, and run the generating function again. Alternately, the variable names in the saved object may be changed directly via a redefinition of save$matnames[[2]]
.
