rep replicates the values in x. Internally, they are generic, so methods can be defined for them (see InternalMethods).. Usage > length(x) [1] 2 > nchar(x) [1] 5 6 Notice that this time, R tells you that your vector has length 2 and that the first element has five characters and the second element has six characters.
In the next code chunk, I’ll create a new vector called my.vec that contains a mixture of numeric and character scalars. To create a character vector with more than one element, use the combine function, c(): x <- c("Hello", "world!") R create repeating pattern in column. In fact, it will create the vector but whole numeric vector will be converted into character vector. strings). R makes life easier by offering you a function for repeating a vector: rep().
