Dear R list I am looking for a function in R that computes the integration of a discrete curve, such as a power spectrum, in a specified interval (in my case, that would be 'power in a certain frequency band'). I found only functions, such as 'integrate', that perform adaptive quadrature on analytic functions, and not on a curve specified as a set of (x,y) pairs. I have the

Dear R users, I have spectral data (say, wavelength vs. extinction coefficient) for which I??d like to calculate an integral (i.e. the area underneath the curve). Suppose the (artificial) dataset is lambda E 1 2 2 4 3 5 4 8 5 1 6 5 7 4 8 9 9 8 10 2 How can I calculate an integral for these values using R? Many thanks for any help! Regards Christoph

Hello list! I would like to fit a distribution to each of the peaks in a histogram, such as this: http://photos1.blogger.com/blogger/7029/2724/1600/DU145-Bax3-Bcl-xL.png . The peaks are identified using Petr Pikal peaks function ( http://finzi.psych.upenn.edu/R/Rhelp02a/archive/33097.html), but after that I am quite stuck. Any idea as to how I can: Fit a distribution to each peak Integrate the

...ion regarding POSIX class objects. I try tu use as.POSIXct for creating and plotting some time series. To be able to set labels for time (x) axis I started with plot(..., axes=FALSE) but although it suppressed all other axes, x axis is still plotted together with labels. Is it a bug? see datum.vyber<-seq(ISOdate(2000,1,1), ISOdate(2003,1,1), by="3 months") plot(datum.vyber,1:13,axes=F) in next command axis.POSIXct(1,at=datum.vyber,format="%Y-%m") axis(2) box() the x axis is overplotted with intended labels. however I just found that I can use plot(datum.vyber,1:13,...

Hi I want to create a vector of colors that are as different from one another as possible. ?rainbow states "Conceptually, all of these functions actually use (parts of) a line cut out of the 3-dimensional color space...". This suggests to me that the resulting colors are all placed on this "line" and are equi-distant along it. The resulting color palette is a range of

I was trying to open up the workspace that you help me write last night, but for some reasons, when I tried to load the saved file R reads "load("C:\\Users\\Documents\\Statistical Learning\\HW1 #3 hint") and then it basically just stopped. I changed the file to a .Rdata file but the problem still persist, any ideas how to fix this? Thank you. -- View this message in context:
