[R] Unexpected Gap in simple line plot
I am getting an unexpected gap in a simple plot of monthly data series. I have created a csv file of monthly climate observations that I store on-line. When I download the csv file and plot one of the series, I get a gap even though there is data for the missing point. Here is a snippet to show the problem. ## Strange plot results link - http://processtrends.com/files/RClimate_CTS_latest.csv; cts - read.csv(link, header=T) ## Simple line plot - gap for no reason plot(cts$yr_frac, cts$GISS, type=l, xlim=c(1982, 1983),xaxs=i, yaxs=i) ## May, 1982 observation missing ## Add points to plot in red, to see if May shows up points(cts$yr_frac, cts$GISS, type=p, col=red) ## yes, May shows up in points ## Look at cts data.frame. No obvious problems to me?? small - subset(cts, cts$yr_frac 1982 cts$yr_frac 1983) small[,c(1,3)] The same problem occurs in the other data vectors (HAD, NOAA, RSS, UAH, etc) I have not been able to figure why I am getting the gap and how to show a continuous line through May, 1982 data points.

[R] Working with source file

They get the plot. What if they'd like to see R script or see contents of data frames, or change the plot parameters? My questions: 1. how can user get list of just data.frames to investigate the data? 2. how can user list my R script in the session so that he/she can adjust it? My R scripts retrieve raw data, process it and organize it for analysis. I'd like the users to be able to save the data, subset, modify data and make their own plots.
