I wanna plot with month,but the x-axis is not in order,such as"Apr","Aug","Nov"..... But I want the order on x-axis to be like "Jan", "Feb", "Mar"........
#change the format of date
date_month <- format(date_1, "%b")
class(date_month)
[1] "character"
head(date_month)
[1] "Jul" "Jul" "Jul" "Jul" "Jul" "Jul"
plot(table(date_month), xlab = "Month", ylab = "count")
I tried this:
x1 <- factor(date_month, levels=c("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov","Dec"))
plot(y ~ x1)
and:
plot(table(date_month), xlab = "Month", ylab = "count")
axis(date_month,labels = c("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov","Dec"))
Doesn't work at all.Can someone help me with this?Many thanks.
in u r code used format to extract months
but use base r function months
u will
get solution easily
If u use format
output is like :
> head(format(date_month$date, "%b"))
[1] "Jun" "Feb" "Mar" "Oct" "Oct" "Aug"
months
will extract the month name fully like below :
> head(months(date_month$date))
[1] "June" "February" "March" "October" "October" "August"
as per u r code do the below :
date_month<-months(date_1)
date_month<-factor(date_month,levels=month.name)
Now plot and try.
sample code :
date_month<-list(date=sample(seq(as.Date('2018/01/01'),
as.Date('2018/11/08'), by="day"), 100))
> head(date_month)
date
1 2018-06-13
2 2018-02-19
3 2018-03-05
4 2018-10-29
5 2018-10-25
6 2018-08-22
