Fix for string subsetting example 

Words in example vector `x <- c("apple", "banana", "pear")` should start with an uppercase letter so the `str_to_lower` example makes sense.

You can extract parts of a string using `str_sub()`. As well as the string, `str_sub()` takes `start` and `end` argument which give the (inclusive) position of the substring:
```{r}
x <- c("apple", "banana", "pear")
x <- c("Apple", "Banana", "Pear")
str_sub(x, 1, 3)
# negative numbers count backwards from end
str_sub(x, -3, -1)
