I am using R 3.5.0 for Mac OS X. Issuing these two commands yields the expected plot. y_duration <- c (301.59050, 387.35700, 365.64366, 317.26150, 321.71883, 342.44950, 318.95350, 322.33233, 330.60333, 428.99516, 297.82066) plot (y_duration, type="l?) Adding Year-Month-Day values for the x axis, and then calling plot (x,y), yields a bizarre plot. Apparently, R does not

Jim, Thanks for responding! I am using the official R 3.5.0 for Mac OS X. This apparently does not include library (plotrix) library(plotrix) Error in library(plotrix) : there is no package called ?plotrix?

Thanks. Regarding axis(1,at=x_yyyymmdd,labels=format(x_yyyymmdd,"%Y-%m-%d")) How do I get the text for YYYY-MM-DD to be drawn vertically, instead of horizontally?

I do not see any difference between the x versus y plot drawn in blue, and the y only plot drawn in red. Is the correct?

Hi Greg, The only reason I included the staxlab function in the plotrix library was to fit all the dates onto the axis. If you want to try it: install.packages("plotrix") Jim On Sun, May 6, 2018 at 9:02 AM, Gregory Coats <gregcoats at me.com> wrote: > Jim, Thanks for responding! > I am using the official R 3.5.0 for Mac OS X. > This apparently does not include library (plotrix) > > library(plotrix) > Error in library(plotrix) : there is no package called ?plotrix? > > Greg > > On May 5, 2018,...

Look at par(las=2) in the graphics package. You will almost certainly have to increase the bottom margin, e.g.: par(mar=c(6,4,4,2) to accomodate the vertical labels.

Since the horizontal axis side=1 is year-month-day, how do I issue an abline command to draw dashed vertical lines, as a background grid, within the graph?s border? Similar to the abline command I call below, in blue, for dashed horizontal lines, as a background grid.
