labelling plots with ancillary data in data.frame
Hi All, I am busy using R to do some regression modelling and have been using plot(x,y,"") to visualise my variables. I would now like to label my points using data stored in the data.frame used for the regression analysis. For example each of my data points is made up of a field measured forest volume value and a remotely sensed vegetation estimate (NDVI). Each point is an enumeration

Regular time series with irregular start and end dates
Dear R users, I have a quick question regarding creating an index for a zoo object. I am using R 2.12 on winxp. I have read through the R archives searching for information on dates and time series analysis and nothing seems to cover my question. I am extracting data from a time series of remote sensing data. The frequency of the data is 16 days which means I cant use ts (ts likes months single

pdf filenames in while loop
Dear R users, I am a remote sensing researcher currently studying the use of LiDAR data for quantifying tree height, in particular I would like to determine the sample size needed to capture and quantify canopy height variability. To do this I have employed the use of automap(), which automatically calculates variograms including reporting the range of the variogram. The program is easy to use

Subsetting a zooreg object using window / subset
Dear R users, I am currently working in subsetting a zooreg() object using either window or subset. I have a solution but it may be a bit cumbersome when I start working with actual data. Your inputs would be greatly appreciated. Example: I have a zooreg() object that starts in 1997 and ends in 2001. This object contains daily data for the 4 years

DES, eBones and crypt availble for non-US!
Hello World! (In particular, that part of it ouside the USA and Canada) I have (with official sanction of the organisation concerned) a LEGAL site for the distribution of crypt and Kerberos code. The secure code (crypt) is _identical_ to the US code. It originated in South Africa and Australia, and has never been to the US, so it is totally kosher. The Kerberos (eBones actually) code stared out

Interpolate irregular time series
Hi all, Issue: I have two datasets, one is a regular time series (rain gauge) with resolution of 10 minutes. The other one is an irregular time series (link). Now I want to analyze the correlation between these two datasets with linear regression. The regular time series is a data.frame and the irregular time series is a zoo object. Problem: For the irregular time series (link) I want also a 10

New package: irregular time-series (its)
I have uploaded to CRAN a new package named 'its' (Irregular Time-Series). It implements irregular time-series as an S4 class, extending the matrix class, and records the time-stamp of each row in the matrix using POSIX. Print, plot, extraction, append, and related functionality are available. Feedback and suggestions are welcome. Giles Heywood
