I only vectors of size 1 are recycled

WebOnly values of size one can be recycled. For compatibility, only a warning is issued for indexing beyond the number of rows. Appending rows right at the end of the existing data is supported, without warning. For compatibility, i can also be a character vector containing positive numbers. WebAs well as implicitly coercing the types of vectors to be compatible, R will also implicitly coerce the length of vectors. This is called vector recycling, because the shorter vector is repeated, or recycled, to the same length as the longer vector. This is generally most useful when you are mixing vectors and “scalars”.
