A scatterplot matrix with outlier and influential errors is produced.
sel.pairs(x, outl = rep(0, nrow(x)), sel = rep(0,nrow(x)),
labs = NULL, log = TRUE, legend=TRUE, title=NULL)
matrix or data frame of the coordinates of points
vector identifying outliers (1 or TRUE means outlier)
vector identifying influential errors (1 or TRUE means influential error)
names of the variables
if TRUE logarithm of x
are plotted
if TRUE a legend is added to first boxplot
an overall title for the plot
The ijth scatterplot contains x[,i] plotted against x[,j]. Outliers are represented as blue circles, influential errors as red circles and points that are both outlier and influential error as cyan circles.
