Subject: [R] Working with string
Hello again,
Let say I have a lengthy character vector like:
CH <- c("aBd", "sTb", "ABD", "dFDasd", "asd", "DFDASD")
Now I want to create a vector like:
CH_New <- c("aBd", "sTb", "aBd", "dFDasd", "asd", "dFDasd") ## the 3rd and
6th element replaced
Basically, the goal is:
If an element has all upper case then it will find another element with all
lower case or mix of upper/lower case. Then the all-upper-case element will
be replaced by that mix. If there is multiple match then chose the first
one.
Can somebody give me any pointer how can I achieve that?
Thanks and regards,
