installing the next version of R while in an older version
Hello - I am a fairly new user of R. I currently have R1.7 installed. I tried to install the KernSmooth package but a message tells me I need R1.8. Is there a way to update to R1.8 while in R1.7 in the same manner that I can use "update.packages", or do I have to install R1.8 in a separate directory and re-install the many packages I have already installed in R1.7?

Wind-data analysis with R?
Hello, are there people outside who use R for analysis of wind-measurement data (meteorological or for planning of wind power stations)? Are there already scripts/modules available for analysing and displaying/plotting wind data in the way it is done in projection/planning of wind power stations? If not, would it be of interest to use R for this, and therefore adapt data-logger output to R (by

need help with smooth.spline
Dear R listers, When using smooth.spline to interpolate data, results are generally good. However, some cases produce totally unreasonable results. The data are values of pressure, temperature, and salinity from a probe that is lowered into the ocean, and the objective is to interpolate temperature and salinity to specified pressures. While smooth.spline provides excellent values at the
