Hello, I have a dataframe called rsts. It looks like this:
> head(rsts)
date Value
1 2012-08-07 45
2 2013-11-10 47
3 2014-01-28 28
4 2013-10-22 50
5 2013-06-13 35
6 2013-05-28 32
where I ran as.Date(date) to get the date column as date objects.
I tried this:
rstst=rsts[-which(rsts$date<2011-03-01),]
to remove dates earlier than March 1, 2011.
But then I tried
> summary(rstst)
but I get this:
date Value
Min. :2006-06-28 Min. :-2.048e+09
1st Qu.:2012-07-27 1st Qu.: 3.300e+01
Median :2013-03-09 Median : 4.100e+01
Mean :2013-01-22 Mean :-5.831e+03
3rd Qu.:2013-08-09 3rd Qu.: 5.400e+01
Max. :2051-04-01 Max. : 1.197e+08
How can the Min be less than March 1 2011?
Thanks
