The syntax of strsplit() function that is used to split a string by delimiter is where Parameter Description x A character vector. The strsplit () method returns the list, where each list item resembles the item of input that has been split. In such a case, the previous R code keeps the last vector element empty. For str_split_fixed, if n is greater than the number of pieces, the result will be padded with empty strings. Description Split the Strings in x into substrings according to the presence of substring split within them. Note that spltting into single characters can be done via split=character(0) or split=""; the two are equivalent as from R 1.9.0. Use strsplit to Split String by Delimiter in R. strsplit is provided with the R base library and should be available on most installations without additional packages. stri_split_lines1 (str) is equivalent to stri_split_lines (str [1]) [ [1]] (with default parameters), therefore it returns a character vector.
