Hi R users, I would like to add year information to each point in a scatter plot. The following example shows what i mean: df=data.frame(year=c(2001,2002,2003),a=c(8,9,7),b=c(100,90,95)) df plot(b~a,data=df) Now, I would like to see which point belongs to 2001, 2002 and 2003 in the above graphic. Thank you very much, ozan [[alternative HTML version deleted]]

...weight"=c(3,2,3,1,1)) x library(Hmisc) wtd.quantile(x$income,weights=x$weight) wtd.quantile(x$education,weights=x$weight) I would like to see the expenditure of each quintile conditional on income, i.e. the education expenditures of the 5th quintile equal to zero. Thanks in advance, -- ozan bakis --__--__--

Dear R Users, I have the following data frame: v1 <- c(rep(10,3),rep(11,2)) v2 <- sample(5:10, 5, replace = T) v3 <- c(0,1,2,0,2) df <- data.frame(v1,v2,v3) > df v1 v2 v3 1 10 9 0 2 10 5 1 3 10 6 2 4 11 7 0 5 11 5 2 I want to add a new column v4 such that its values are equal to the value of v2 conditional on v3=0 for each subgroup of v1. In the above example, the
