Hi Greg,
What you are getting there is a factor, interpreted as a 1:n sequence
based on the sort order of your "dates". Here's a way to get dates on
your x-axis in the format you want:
x_yyyymmdd<-as.Date(c("2018-04-25","2018-04-26","2018-04-27",
"2018-04-28","2018-04-29","2018-04-30","2018-05-01","2018-05-02",
"2018-05-03","2018-05-04","2018-05-05"),format="%Y-%m-%d")
plot(x_yyyymmdd, y_duration, type="l",xaxt="n")
library(plotrix)
staxlab(1,at=x_yyyymmdd,labels=format(x_yyyymmdd,"%Y-%m-%d"))
