[R] Retrieving the matched data frame from Matching?
I'm trying to use the Matching package to create a matched dataset but I'm having trouble retrieving the data frame where the comparison cases are identified. Could someone please give me a pointer on how to do this? The call was a simple one and seems to have worked with no errors ... m8 <- Match(TR = Tr8, X = X8, M = 2) summary(m8) Appeciated!

[R] Help with grouped barplot
Given the data structure below, how can I create a bar plot for the values of
disc for each area grouped by year?
bar <-structure(list(year = c(2003, 2003, 2003, 2003, 2003, 2003, 2003,
2007, 2007, 2007, 2007, 2007, 2007, 2007), area = structure(c(6L,
4L, 1L, 2L, 3L, 5L, 7L, 6L, 4L, 1L, 2L, 3L, 5L, 7L), .Label = c("AK",
"ID", "MT", "NW", "OR", "US", "WA"), class = "factor"), disc = c(55.8,
62.6, 54.3, 56.9, 52.8, 66.7, 64.8, 59.5, 64.8, 65.8, 61.4, 60.6,
66.3, 65.5)), .Names = c("year", "area", "disc"), class = "data.frame",

[R] Help spruce up a ggplot graph
