[R] Date Conversion Problem

i have written an R script which allow me to plot the number of Covid-10 cases reported by he state of Ohio. In that se t of data the date format is in the form -mm-dd. My script uses: datebreaks <- seq(as.Date("2020-01-01"), as.Date("2020-08-10"), by="1 week") . .

Re: [R] add trailing dates with rbind

Hi Frederik, (short answer) modify the assignment statement to agg_d_h <- rbind( agg_d_h, data.frame(Group.date=next_date,x=0) ) Note: replace x=0 by your-variable-name=0 Note: left-hand-side of the assignment statement should be agg_d_h (longer answer) Your approach is far from the b

[R] add trailing dates with rbind

I am having a hell of a time, this must surely be simple to solve…. Basically I want to add trailing dates to datasets with differing starting dates so that across datasets I have the same starting date. # make dataset with the same starting date start_date = as.Date("2020-03-01") d_start_date =
