我可以在 dplyr 对面使用 join 吗？

Question

I do not want to use all variables in data frame. I was thinking of something like this, but it comes up with an error.

df1 %>% 
full_join(df2, by = 'DATE':'Vz').

Both data frame contain the same variables from DATE to Vz. I am interested in bringing the non-zero values of df2 to df1.

Thank you.

You can join by multiple columns with dplyr. Let me know if this answers your question:

library(dplyr)

full_join(df1, df2, 
  by=colnames(d1)[which(colnames(df1)=="DATE"):which(colnames(df1)=="Vz")])
