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.

Jim, Thank you very much! How do I use the axis command for side=1 to label the x horizontal axis, in the format="%Y-%m-%d? style? Greg 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, 258.23166) x_yyyymmdd <-as.Date(c ("2018-04-25", "2018-04-26",

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?

Helo Greg - I got it with help of your code and I would like to add the value into the boxplot chart. How to do that. y_duration <- c (16.438, 15.321, 12.700, 12.397, 10.795, 9.928, 10.386) On May 09, 2018, at 10:06 AM, Jayaganesh Anbuganapathy <jai6561 at icloud.com> wrote: Actually I would like to get an output on the below snapshot.

Jim, That you very much! How do I instruct staxlab to label once every n days, rather than labeling every day? Greg > On May 5, 2018, at 6:50 PM, Jim Lemon <drjimlemon at gmail.com> wrote: > > staxlab(1,at=x_yyyymmdd,labels=format(x_yyyymmdd,"%Y-%m-%d")) [[alternative HTML version deleted]]

Hi Greg, By default, the "axis" function puts the labels on one line and drops labels that would overlap. When you have labels that are all the same length, this usually results in every second, or third, or fourth label being displayed. So you can probably get what you want by not using staxlab. However, if you really want to use staxlab, try this:

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?

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",

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.

Hi Greg, Easy: plot (x_yyyymmdd, y_duration, type="l", xaxt="n", yaxt="n", ylim=range(240,480)) abline (h=c(240,270,300,330,360,390,420,450,480,510,540), lty=2, lwd=1.0, col="grey40") axis(1,at=x_yyyymmdd,labels=format(x_yyyymmdd,"%Y-%m-%d"))

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?

Hi Greg, This is because both plots have equally spaced x values. To see the difference, try this: plot (x_yyyymmdd, y_duration, type="l", xaxt="n", yaxt="n", ylim=range(240,480), xlab="", ylab="", col="blue") axis(1) plot ( y_duration, type="l", xaxt="n", yaxt="n", ylim=range(240,480),

Actually I would like to get an output on the below snapshot. I have tried various method like points, labels.. but nothing works. Attached is the data for your reference.

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

What I want to do is create a horizontal bar chart matrix for a set of data that have a common set of variables (e.g., % of As, % of Bs, etc.) listed on the Y-axis and groups (e.g., Classes) on the X-axis. The key here is that the bars for each individual class plot are "centered" rather than left or right-justified. In archaeology plots similar to this are called battleship curves or

Dear R list, I am a newbie to R and programming itself, so my question may be easy to answer for you. I wanted to create a scatterplot and i used the following code: par(mar=c(10, 4.1,4.1,2.1)) plot(q$location,q$points, , las=2, cex.axis=0.5,xlab="", ylab="" ) #location are character strings, there are about 70 locations #points are numeric, there are more than 4 points for

Hi Jim, Thanks for your help, I really appreciate it. Perhaps I'm misunderstanding, but does this formula run different ajustment values for this function? logit(p = doc$value, adjust = 0.025) I'm looking to plot the p-values of different adjustment values.
