Insert text in data.frame
Dear R-helper,
I wonder if anyone can help me. I am trying to convert a dataset to a
format recognizable by a software onboard a research vessel but I am
having problems with some steps.
I have a data frame as follows:
Conc Lat Lon Depth
Point0000 56.25 -5.65 70
Point0001 56.55 -5.35 85
Point0002 56.25 -5.65 65
Point0003 56.37
