delete_start_with.Rd

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.

Usage

delete_start_with(s, vec)

Arguments

s

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

vec

a vector of strings with unwanted starting strings (specified by s).

Value

string(s) with deleted patterns from the start.

#> [1] "hello"
delete_start_with("X_",c("X_hello","hello2"))
#> [1] "hello"  "hello2"
delete_start_with("X_",c("X_hello","hello2","X_hello3"))
#> [1] "hello"  "hello2" "hello3"
