What you are getting back in 'feb_no_29' is a data frame which can not be
used for indexing. Do 'str(feb_no_29)' and see what you set. What you
probably want to do is to use 'which' to find out which rows match the
criteria and then delete them:
feb_29 <- which((Pooraka_data$Month == "2") & (Poo
Hi R-expert,
I try to eliminate 29 Feb but I got an error message below:
feb_data1 <- Pooraka_data[Pooraka_data$Month=="2",]
feb_28days <- feb_data1 [feb_data1$Day=="28",]
feb_29days <- feb_data1 [feb_data1$Day=="29",]
## delete 29 Feb
feb_no_29 <- feb_data1 [-(feb_29days),]
feb_no_29 <- feb_data1
