Joachim,
This is definitely useful! By the way would you be willing to cover the "here" package that apparently eases the "pain" of locating and referring to files.

Hye Sir, I have problems in R again. My dataframe consist of Column “Dates” and “Water Level”. But the ‘dates’ are not arrange accordingly where row one is ‘12-1-1991’ and row two is ‘13-12-1997’(Just an example). How can I rearrange the dates alongside its water level data? My data is large from year 1960-2020. I’m so sorry if I disturb you

Do you know anything about awk commands? I am trying to get the frequency of all lines of DNA input from a txt file? For example, if pattern GCGCTTAATA is within a list 10 times, I need for the read out to list the 10 as a frequency.
