I was trying to recreate this kind of timeline plot: http://www.vertex42.com/ExcelArticles/create-a-timeline.html
As you can see in their excel example, the events are nicely placed out on both sides of the timeline axis. AFAIK there is no function to do this nicely in R-project. Furthermore, graphics and lattice packages are unable to draw the x-axis in the middle of the plot. (datapoints cannot be plotted below the axis, as in the Excel example). My question: Is there a function to draw the x-axis inside the plot? (at a certain vertical position?) Is there a function for the whole timeline plot that I do not know about? I tried to visually replicate the plot using additional elements to create my own x-axis (code below). I have placed the x-axis ticks on a fixed y-height (-0.1 and -0.05), but this might look badly with a different dataset or at other image proportions. I'd rather do this with a dedicated package function ( like axis() ). -- mrgomel ----------------------- Below is my example code in R: the_data <- structure(list(eventtime = c(1914L, 1917L, 1918L, 1939L, 1945L, 1963L, 1989L, 2001L, 2003L), impact = c(1, -.5, 0.8, 1, 0.8, 0.5, -.5, 0.5, 1), label = structure(c(8L, 7L, 4L, 9L, 5L, 2L, 3L, 1L, 6L), .Label = c("9/11", "Cuban crisis", "end of communism", "end WW1", "end WW2", "Iraq war", "start of communism", "WW1", "WW2"), class = "factor")), .Names = c("eventtime", "impact", "label"), class = "data.frame", row.names = c(NA, -9L)) plot(the_data$eventtime, the_data$impact, type="h", frame.plot=FALSE, axes = FALSE, xlab="",ylab="", col="grey") text(the_data$eventtime,the_data$impact, the_data$label) #axis(1) abline(h=0,lwd=2) text(axTicks(1),-0.1, axTicks(1)) points(axTicks(1),rep(-0.05,length(axTicks(1))), type="h") [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
