Hello!
I am trying to subset a dataset by separating them between the maximum value in the first column. One dataframe will be from the lowest to highest value (dat.down), and the other will be all the other values (dat.bottle). The code works with data.down, but for dat.bottle, I get the following error message:
Error in `[.data.frame`(dat.3, deepest:length(dat.3[, 1]), c("Depth (m)", :
undefined columns selected
Can anyone help me figure out what's wrong? Here is my dataset and code:
