delete_start_with function

Deletes a pattern from the start of a string, or each of a vector of strings.

delete_start_with is used for clean the column names in raw data. For example, R adds "X" at the start of variable names. This function deletes "X_"s from the column names. This can happen if the raw data have column names such as "_CASE_ABX". Check clean_perch_data() for its actual usage.

Arguments

• s: the pattern (a single string) to be deleted from the start.
