...ries. 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 i...

Hi all, A friend just sent me this: http://www.mathworks.com/company/events/webinars/index.html?id=&language=en <http://www.mathworks.com/company/events/webinars/index.html?id=&language=en>And asked me if there is something of the like in the R community. Does anyone know of such a think ? Cheers, Tal ----------------Contact

...o use them efficiently. Below I have included a application of "reshape" that is rather clunky and I'm hoping someone can offer advice on how to use reshape (or melt/cast) more efficiently. #For this example I am using climate change data available on-line file <- (" http://processtrends.com/Files/RClimate_consol_temp_anom_latest.csv") clim.data <- read.csv(file, header=TRUE) library(lubridate) library(reshape) #I've been playing with the lubridate package a bit to work with dates, but as the climate dataset only uses year and month I have #added a "day" to...

I am trying to download and open an on-line netcdf file. I'm using Windows XP and R 2.11.1 Here's my script library(ncdf) link <- "http://ibis.grdl.noaa.gov/SAT/SeaLevelRise/slr/slr_sla_gbl_free_all_66.nc" dest <- "C:/temp/slr_sla_gbl_free_all_66.nc" download.file(url=link,destfile=dest) nc1 <- open.ncdf(dest) The file appears in my C:/temp

I am trying to build an easy to use climate data analysis tool kit that will let non-R users run my detailed r script with minimum R learning curve effort. Here's an example: link <- "http://chartsgraphs.wordpress.com/files/2010/01/nsidc_trend_plot_2.doc" source(link) This lets user run my R script stored at site 1 and work with data stored at site 2 without having to worry

hi, is it possible to draw a plot inside another plot f.e in the upper right corner. I do not mean the possbility par(mfrow = c(2,2). Kind Regards Knut

The pretty picture that I saw at: http://chartsgraphs.wordpress.com/2009/02/09/r-panel-chart-beats-excel-chart/#more-1096 inspired me to try something similar. The code that I wrote is: ------snipsnip--------------------------------------------------------------------- M <- structure(list(date = structure(c(13634, 13665, 13695, 13726, 13757, 13787, 13818, 13848, 13879, 13910, 13939, 13970,

hi folks, Bit of a newbie, but I've spent a fair bit of time looking for an answer on this, with no joy. Can anyone help me? Dataset: A single column of values in a csv file (eg. 52, 53, 54, 85, etc) Goal: In Minitab, you have what they call a dot plot. It's a histogram, where a single dot represents a set of identical values (eg. 57, 57, 57 would be one dot). Multiple dots are

I am trying to get monthly means for a daily data series using zoo(). I have found an odd problem, that seems to be caused by zoo()'s handling of leap years. Here's my R script with 2 methods (freq=365, 366) for aggregating the daily data to monthly series: library(zoo) J_link <- "http://www.ijis.iarc.uaf.edu/seaice/extent/plot.csv" JAXA_data <- read.table(J_link,
