I have a dataframe in the following format
df_151=as.POSIXct("1976-09-03 23:00:00") df_151=as.data.frame(df_151) colnames(df_151)=c("datetime") df_151
I am able to add a row with the following code
As I am dealing with 1000s of rows, this code took me 4-5 min to complete it with other operations.
I will be grateful if anyone could provide an alternative way to get faster or how can I avoid using $ in the above code.
