Colleagues
Assume that I have a vector containing some text strings, some of which contain
a particular character. I could like to apply "toupper" to the text before the
character. For example (in this case, "|" is the particular character):
ORIGINAL:
TEXT <- c("aaaa", "bbb|cc", "|ddd")
AFTER APPLICATION OF toupper:
TEXT <- c("AAAA", "BBB|cc", "|dddd")
I could loop through each element, strsplit at the character, apply toupper to
the first component, then paste each element together. But, I hope that there
is a simpler means to accomplish this.
Thanks in advance.
