str_diff(x, y)
x |
a single string |
y |
a single string |
an integer vector containing the index of all mis-matched characters in the first string.
# strings to compare x <- "once upon a time" y <- "once upon a time there was" z <- "once upon two times" # diff: x - y d <- str_diff(x, y) d str(d) # other comparisons str_diff(y, x) str_diff(x, x) str_diff(x, z) str_diff(y, z)
