Very nicely explained, Joachim. I have a data frame that has 4000+ rows and 20+ columns. 18 of the columns contain readings for each of the 18 sensor nodes in the product. The headers (for those 18) are labelled n1..n18 Is there a way I can programmatically refer to a cell on row x by reference to the column name ? Something like value
Found answers to my questions: %>% select(Time, n1:n18) gives me test time and the columns of interest. Link:- ruclips.net/video/tSVX8-NZ9OI/видео.html "Environmental science with Dr Lisa"
Hey Bob, thanks a lot for the kind words! Personally, I would extract all the columns you want to plot to a new data frame. I think this is a matter of taste, though.
