Question concerning "pastecs" package
Hi I just installed the pastecs package and I am wondering: is there an english (or german) translation of the file pastecs.pdf? If not, is there an explanation somewhere of the object of type 'turnpoints' as a result of turnpoints(), especially the "info" field? Thanks, Rainer -- NEW EMAIL ADDRESS AND A...

date conversions in pastecs

Turnpoints (pastecs): How to specify a limit on the number of tur npoints?
Hello, I'm trying to get a few turnpoints for a financial time series. There is a function in pastecs that does that. However, I get a large number of turnpoints: library(pastecs) data(EuStockMarkets) dax <-EuStockMarkets[,1] plot(dax) turnp <-turnpoints(dax) summary(turnp) #gives 925 peaks/pits!!! How can specify to get only 30 turnpoints? Second question: the extract function extra...

problem with applying regul function (pastecs)
Hi, I'm trying to analyse some time series data on dissolved organic nitrogen. Because it has gaps in it, I try to interpolate (linear) with the regul method from the pastecs package. I have a number of stations with measurement series in a matrix constructed from a data frame with the unstack method (temp) I also used the unstack method to make a similar matrix for the time points (time) Now I have two matrices with the names of the stations as column headers....

Some questions about package "pastecs" and "stats"
...the trend (the residual is a trend-free signal)? For instance, a package implementing SSA, sometimes enters an endless loop. It keeps detecting trend in the residual signal no matter how many times the removing procedure is run and the signal reconstructed. 3. Question about package "pastecs": Are there any criteria helping with the choice of proper values for parameters "order", "times" , "type" for functions "decaverage" and "decmedian" ? 4. Question about package "stats": Are there any criteria helping w...

Registration
Hi, I have a question to post. But I have a problem finding the appropriate forum. Some of the FAQ on pastecs are answered by R-help@stat.math.ethz.chmailing list. I searched to see if this mailing list requires registration or not. There was no information about that. I am a registered member of R- help general mailing list but I am aware it is better to post my question to a specific group in some cases...

Irregular Time Series Issue
...I have an irregular time series of the form : Time Data Time1 Data1 .... 1 b 1 e 7 g 4 i NA NA 5 k NA NA NA NA ... (the columns have varying length of NAs after a certain point) Converting this to regular time series with Pastecs does not seem to work, when I see the entire data as a single series. So I remove the NAs and deal with one series at a time in a loop. Any suggestions ? Thanks A. Mani -- A. Mani Member, Cal. Math. Soc

Turnpoints
Good evening to everybody. I have a data of four columns - three of the columns represent date while the fourth is counts. Setting 4000 as my minimum point/value, I wish to find out the number of counts that are less or equal to 4000 and the dates they occur. I have installed pastecs and have been trying to use turnpoints function to do this. I have not been much lucky. I am a still learning. I have added part of my data here where y stands for year, m month, d day and lastly the count. I would be grateful to anyone who could show me the way the do this. Best regards Ogbos y...

how to make a table of summary statistics
Dear R-listers, I am a newbie with R and I am struggling with something I consider very basic. I wish to produce a table (to import in a latex file) of summary statistics, but for as much as I've been looking around and trying various alternatives (plyr, reporttools, pastecs and Hmisc) I haven't found what I am looking for. Probably I am doing something wrong, but I can't figure out what. Let's make up three simple variables: var1 <- runif(1000) var2 <- runif(1000) var3 <- factor(rep(1:2, 500), labels = c("m", "f")) and let...

function masking and gmp questions
Hi, Here's the problem I ran into: the gmp package has a method for apply() so it masks the base::apply function. With gmp installed, I tried to run the function turnpoints() from the pastecs package. It fails because it calls apply() internally, like this: apply(mymatrix,1,max,na.rm=TRUE) , but the code in the gmp package which sets up the operator overload for apply() strictly limits the arguments to the first three (a matrix, a dimension, and a function). I get, no surprise:...

spatial-time smoothing
Hi all, I'm looking for to interpolate hourly temperature date collected from more than 140 automatic weather station (irregularly spaced) using 4 independent variable: 1-2) geografic coordinates (x,y) (from DEM - 40m) 3) altitude (z) (from DEM - 40m) 4) solar radiation (from a model calculated with grass: r.sun) In addition, I would like to use also "time" variable (e.g.: hours).
