Hello ! I'm trying to remove lines in my data frame where values of columns 1 and 3 are the same. But if column 2 are differents between these lines, i wanna merge them. All the data frame contain characters, no integers. Is there a fast way to do that ?
a reprex would make it easier to assist you as it would save a helper work in inventing examples of your data to demonstrate solutions on. FAQ: How to do a minimal reproducible example ( reprex ) for beginners
Are you familiar with the tidyverse package ? there are convenient functions therein.
filter() for dropping rows that meet conditions. mutate() to make new variable (perhaps to hold condition flags), case_when() is often useful for multivalue conditions, and base paste() function is oft used for merging character strings.
