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,
