varImp function.varImp if using non-default number of I-splines.formatsitepair function to control whether site-pair attributes are printed.summary function.sitepairformat function from actually subsampling the site-pair table.gdm model object that broke the predict.gdm function.Substantial update to the package structure to use devtools, roxygen2, etc. development tools.
Fixed a number of bugs associated with using non-default numebrs of splines.
Add two new functions gdm.partition.deviance and gdm.crossvalidation. The gdm.partition.deviance functions partitions deviance explained by different sets of predictors into unique/shared components. The gdm.crossvalidation function produces a number of model evaluation metrics using bootstrapping.
summary now provides the sum of the I-spline coefficients (indicator of predictor importance) and lists variables from highest sum to lowest.
plot now plots I-splines in order from highest sum of coefficients to least.
