Starting with year-month-day, for the variable gallons, I can easily plot the variable gallons, while disregarding the date. gallons <- c (15.973, 18.832, 17.392, 14.774, 19.248, 14.913, 15.226, 14.338, 18.777, 19.652) plot (gallons, type="l", xlab="X label", ylab="Y label", col="blue?) How do I direct R to plot the variable gallons, at the appropriate, irregularly-spaced places on the X axis, while paying attention to the year-month-day? format = "%Y-%m-%d? 2020-01-05 15.973 2020-02-15 18.832 2020-03-10 17.392 2020-05-04 14.774 2020-06-21 19.248 2020-08-01 14.913 2020-08-27 15.226 2020-09-28 14.338 2020-11-09 18.777 2020-12-11 19.652 [[alternative HTML version deleted]]
Hi Gregory,
Here's a start:
gcdf<-read.table(text="2020-01-05 15.973
2020-02-15 18.832
2020-03-10 17.392
2020-05-04 14.774
2020-06-21 19.248
2020-08-01 14.913
2020-08-27 15.226
2020-09-28 14.338
2020-11-09 18.777
2020-12-11 19.652",
header=TRUE,stringsAsFactors=FALSE,
col.names=c("date","gallons"))
gcdf$date<-as.Date(gcdf$date,"%Y-%m-%d")
plot(gcdf$date,gcdf$gallons,main="Gallons by date",
xlab="Date",ylab="Gallons")

By converting the character date data into a time-like type... e.g. ?as.Date and plotting y-vs-x.
