Dear R Users,
I have two data frame. Each of them has three columns but the number of rows is different. I would like to find the row indices of the longer data frame where its values exist in the other data frame. I tried the following:
ind = which(as.numeric(Results[,1]) %in% as.numeric(Hour.mean[,1]) & as.numeric(Results[,2]) %in% as.numeric(Hour.mean[,2]) & as.numeric(Results[,3]) %in% as.numeric(Hour.mean[,3]) )
but it does not give correct values. Could someone suggest me a solution?
