reshape to wide format when more than two columns

Apologize if this question has been asked before, i didn't find nothing similar. So, it's trivial to reshape when we have something like

id status1 value
1  active   1
2  close    23

result after reshaping will be 

id active close
1  1      23

but, what if our table have more than one status column? and we need to reshape by status1, and status2 columns?

id status1 status2 value
1  active  complete 2
2  close   overdue  3

Expecting result

id active close complete overdue

Home the question is clear. Any comments or suggestions will be highly appreciated.

Not quite sure what you're after, but maybe this could work.

example:

library(reshape2)

df <- as.data.frame(cbind(c(1,2,3), c("Active", "Close", "Active"),c("one", "two", "one"), c(5,6,7)))
colnames(df) <- c("id", "status1", "status2", "value")

df1 <- dcast(df, id ~ status1)
df2 <- dcast(df, id ~ status2)

merge(df1, df2)

Here's another option:

library(reshape2)
df <- read.table(header=T, text="id status1 status2 val
1  active  complete 2
2  close   overdue  3")
recast(df, id~value, id.var = c(1, 4), value.var = "val")
#   id active close complete overdue
# 1  1      2    NA        2      NA
# 2  2     NA     3       NA       3
