Dear list: I have two dataframes, say dat1 and dat2. Each has several variables but 3 of each are common in both, (say v1, v2 and v3). v1 and v2 are factores while v3 is numeric. Now, I need a subset to extract the rows in which v1, v2 and v3 are the same in both dataframes. I tried: subset(dat1, dat1$v1 %in% dat2$v1 & dat1$v2 %in% dat2$v2 & dat1$v3 %in% dat2$v3) I dont know why, but this is not working as I was expecting. Any suggestion to improve my code? Thanks in advance Justin -- partofy at inoutbox.com --
This seems to work for me:> set.seed(1) > df1 <- data.frame(v1=factor(sample(1:4,20,TRUE)), v2=factor(sample(1:3,20,TRUE)), v3=sample(1:3,20,TRUE)) > df2 <- data.frame(v1=factor(sample(1:2,20,TRUE)), v2=factor(sample(1:2,20,TRUE)), v3=sample(1:2,20,TRUE)) > subset(df1, (df1$v1 %in% df2$v1) & (df1$v2 %in% df2$v2) & (df1$v3 %in% df2$v3))v1 v2 v3 2 2 1 2 5 1 1 2 11 1 2 2 14 2 1 1>Exactly what problems are you having?

Dear list:
I can now reproduce with a bit of my real data, the problem I asked for
your help yestarday:
time1<- as.Date(c("2006-01-03", "2006-05-03",
"2006-05-04",

"2006-09-15", "2006-10-30", "2006-11-08",
"2006-11-14", "2006-11-20"))
volume1<- c(7312.5, 3352.5, 4252.5, 3825.0, 2700.0, 585.0, 810.0,
3015.0, 2925.0, 1102.5, 2632.5, 652.5, 1417.5)
dat1<- data.frame(v1=time1, v2=volume1)
time2<- as.Date(c("2006-05-03", "2006-05-09",
"2006-05-04",
"2006-05-08", "2006-07-14", "2006-07-10",
"2006-05-12", "2006-05-17",
"2006-05-19", "2006-05-26", "2006-05-29",
"2006-05-18", "2006-05-22",
"2006-07-03", "2006-07-05", "2006-07-06",
"2006-07-04", "2006-07-24",
"2006-07-12", "2006-07-18"))
volume2<- c(4522.5, 7065.0, 3622.5, 7875.0, 3532.5, 3667.5, 6480.0,
4612.5, 4005.0, 10350.0, 5310.0, 6345.0, 7177.5, 5107.5, 4837.5, 3352.5,
4050.0, 6772.5, 7290.0, 5625.0)
dat2<- data.frame(v1=time2, v2=volume2)
subset(dat1, v1 %in% dat2$v1 & v2 %in% dat2$v2)
v1 v2
2 2006-05-03 3352.5
This is not what I expect since this row is not present in dat2 and I
just want records present in both dataframes.
Help?

Not exactly. I need something to subset ONLY rows common to both dataframes. In the provided example, dat1 and dat2 have no common rows so I would expect: [1] v1 v2 <0 rows> (or 0-length row.names) But I can?t do it...
