What is the error message? What does 'str(MyData)' show? I read your data in and it worked fine.
x <- read.table(textConnection(" name value times
+ 1 A1 2 2006-05-12 + 2 A2 3 2006-05-16 + 3 A3 1 2006-05-12 + 4 A4 4 2006-05-12 + 5 A5 2 2006-05-16 + 6 A6 1 2006-05-12"), header=TRUE)
str(x)
'data.frame': 6 obs. of 3 variables: $ name : Factor w/ 6 levels "A1","A2","A3",..: 1 2 3 4 5 6 $ value: int 2 3 1 4 2 1 $ times: Factor w/ 2 levels "2006-05-12","2006-05-16": 1 2 1 1 2 1
x$times <- as.POSIXct(as.character(x$times)) str(x)

Not without more information. (for example, the full text of the error message; you should also use traceback(), verify that MyData$times has the class you expected, ditto for MyData$value) Please take a look at the posting guide.
Thanks alot,
Samuel
