Hello R-Helpers,
I would like to generate the frequencies of dates (data.RData).
str(data)
Date[1:43748], format: "2001-01-01" "2001-01-01" "2001-01-01" "2001-01-01"
...
test <- hist(data,"days",freq=T)
> test$counts
[1] 27 17 12 15 6 4 5 13 5 13 15 9 7 10 11 21 10 10 9 11 15 7 10
14
but the count is wrong, because i have only 9 times 01/01/2001 etc.
> data[1:30]
[1] "2001-01-01" "2001-01-01" "2001-01-01" "2001-01-01" "2001-01-01"
[6] "2001-01-01" "2001-01-01" "2001-01-01" "2001-01-01"
"2001-01-02"
[11] "2001-01-02" "2001-01-02" "2001-01-02" "2001-01-02" "2001-01-02"
[16] "2001-01-02" "2001-01-02" "2001-01-02" "2001-01-02" "2001-01-02"
[21] "2001-01-03" "2001-01-03" "2001-01-03" "2001-01-03" "2001-01-03"
[26] "2001-01-03" "2001-01-03" "2001-01-03" "2001-01-03" "2001-01-03"
Now, when i give R the breaks.
> br <-
seq(as.Date("31.12.2000",format="%d.%m.%Y"),as.Date("01.01.2012",format="%d.%m.%Y"),by=1)
> test2<- hist(data,br,freq=T)
> test2$counts[1:10]
[1] 12 15 17 12 15 6 4 5 13 5
In this case, neither get the right counts but limiting i get the correct
counts:
> test3<- hist(data[1:50],br[1:6],freq=T)
> test3$counts
[1] 9 11 13 9 8
I hope someone can help me with this problem.
Thank you very much!!
Best regards,
Dominic
