Hello,
if we suppose that
times <- c("2006-05-14", "2006-06-12",
"2006-06-12", "2006-05-14", "2006-05-14",
"2006-06-12")
value <- c(2,3,1,4,3,1)
then with
plot(times, value)
we have two boxplots in one graph for 2006-05-14 and 2006-06-12 respectively!
Is it possible to have them in a scatterplot? and if I sort the data as
x <- data.frame(times, value)
x <- x[order(times),]
Is it possible to create a new variable which contains 1 for 2006-05-14 and 2
for 2006-06-12?
Thank you very much in advance!

I think you mean boxplot( value ~ times)> > we have two boxplots in one graph for 2006-05-14 > and 2006-06-12 respectively!

However if you do times <- as.Date (c("2006-05-14", "2006-06-12", "2006-06-12", "2006-05-14", "2006-05-14", "2006-06-12")) then you can.> and if I sort the data as > > x <- data.frame(times, value) > x <- x[order(times),] > > Is it possible to create a new variable which > contains 1 for 2006-05-14 and 2 for 2006-06-12? >y <- ifelse(x[,1]=="2006-05-14", 1 , 2) x <- cbind(x,y) ; x It was not clear exactly what you wanted to plot so this may be closer to what you wanted than converting to as.Date and ploting plot(x[,3],x[,2], col="red",xaxt="n", xlab="times", ylab="value") axis(side=1, at=c(1,2), labels=c("2006-06-12", "2006-06-12"))
