I made a list of dates called newDat that looks like the following:
> newDat
  [1] 4.2.20   4.3.20   4.4.20   4.5.20   4.6.20   4.7.20   4.8.20   4.9.20  
  [9] 4.10.20  4.11.20  4.12.20  4.13.20  4.14.20  4.15.20  4.16.20  4.17.20 
 [17] 4.18.20  4.19.20  4.20.20  4.21.20  4.22.20  4.23.20  4.24.20  4.25.20 
 [25] 4.26.20  4.27.20  4.28.20  4.29.20  4.30.20  5.1.20   5.2.20   5.3.20  
 [33] 5.4.20   5.5.20   5.6.20   5.7.20   5.8.20   5.9.20   5.10.20  5.11.20 
 [41] 5.12.20  5.13.20  5.14.20  5.15.20  5.16.20  5.17.20  5.18.20  5.19.20 
 ...
I subsequently plot my data by using the following code
plot.ts(as.Date(newDat,"%m.%d.%y"), casesDifferenced, type = "l",
        xlab = "Date")
But my x-axis dates are now showing up properly as shown in the image below.
What am I missing here?
