Date Conversion Problem
Extra packages are not needed. My question is: why change the character representation at all? See the format argument of ?as.Date.
as.Date("20010102",format="%Y%m%d")
[1] "2001-01-02" ## the default format for the print method for Date objects Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into it." -- Opus (aka Berkeley Breathed in his "Bloom County" comic strip )

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 yyyy-mm-dd.
My script uses:
datebreaks <- seq(as.Date("2020-01-01"), as.Date("2020-08-10"), by="1
week")
.
.
.
+ scale_x_date(breaks=datebreaks)
+ theme(axis.text.x = element_text(angle=30, hjust=1))
to plot the data.
The COVID Tracking Project publishes considerably more data than does
the state of Ohio. However, The project supplies daily statistics using
the date format YYYYMMDD.I have done some searching, but I can't seem to
find a solution (that I can understand).
How can I change the date forma from YYYYMMDD tp YYYY-MM-DD?
Thanks is advanced.
