I assume this has been asked multiple times but I couldn\'t find the proper words to find a workable solution.

How can I spread() a data frame based on

Answer 1

Your entry data frame is not tidy. You should use gather to make it so.

gather(df, key, value, -id, -time) %>%
  mutate(key = paste0(key, "time", time)) %>%
  select(-time) %>%
  spread(key, value)
