[R] How to eliminate perticular date

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

Re: [R] How to eliminate perticular date

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)

Why dont you use the rattle GUI for data selection ? Regards, Ajay On Mon, May 12, 2008 at 6:24 AM, Roslina Zakaria [EMAIL PROTECTED] wrote: 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
