cbind(...)
rbind(...)data.table because of this feature in cbind : cbind(DT,DF) dispatches to the S3 method cbind.data.frame even
when cbind.data.table is provided by data.table. Therefore, we have masked these
functions. Warning messages will be presented to the user (by R) when the data.table
package is loaded.
If the first argument is not a data.table, then they revert to the base versions.
