Hi Users, I have daily series of data from 1962 - 2000, with the data for February 29th in leap years excluded, leaving 365 daily values for each year. I wish to convert the daily series to monthly series. How can I do this using the zoo package or any other package? Thanks ZABLONE OWITI GRADUATE STUDENT Nanjing University of Information, Science and Technology College of International

Dear Users, I have a monthly data for a number of years(1960-2007) for a number of stations and i wish to extract sesonal time-series for the months of March-May and October-November for very station. I have read this data with read.table in R with stations as columns and time (months) as rows. My attempt to aggregate with the zoo package using the function as.yearqtr failed since this sums

Dear users, I have monthly station data (44) stations data for 45 years which I have read in R using read.table. the data is in the format: Year Month Station1 Station2 ...................................... Station 44 (i.e the column names in the 1st row), I also have the latitude and longitude of the stations in a separate file in R (in the format : Station LAT LON). I wish to

Dear users, I have several columns of data (each column containing monthly data for a particular year from january - december) . I would wish to combine the columns to get a Single column of continuous data as shown in (b) below. I have read this data as table in R (a) Data example Year 1903 1904 1905 1906 Jan 125.0 30.0 113.0 5.0 Feb 128.0 100.0 70.0 388.0

Dear all, I am plotting daily data from 1950 to 2000 and I wish to have the time in X-axis to indicate years and NOT days (i.e 1950 1951,......,2000 instead of 1,2, 3, ......). How do I set the x-axis to show years instead of days.

Hi Users, I want to fit the maximums of a data series with a cubic spline. How do I go about this in R. I failed to figure out how I can use the mgcv library to do this. Thanks ---------------------------- ZABLONE

{again a message that was sent to owner-r-help (which is me, currently) why on earth ???!??!? reply to R-help or the original sender Brett Presnell; } I'm teaching a categorical data analysis course this term, and a minor "problem" has resurfaced that I have often thought about before. This applies equally to Splus I suppose, but my undergrads aren't using Splus. It

Hello, I have a question about device number extension in "e2fsprogs-1.35". In Linux kernel 2.6, device number is extended from 16-bit to 32-bit. All utilities and libraries should make corresponding extension for this new feature in kernel 2.6. Following operation defines type "kdev_t" as "unsigned short" type, thus the device number has only 16-bit. In file

Dear all, I hope to remove a whole column from a data frame or matrix (> 2000 columns). All value in the column are same. The first thing is to select those columns. For instance, I hope to remove the V3~6 column, for all the value in those colume is zero. V3 V4 V5 V6 V7 V8 V9 V10 1 0 0 0 0 0.000 0.000 0.000 0.000 2 0 0 0 0 0.000 0.000 0.000 0.000 3 0 0 0

Dear all, I found pls.pcr package will give different results if the data are centered and scaled using scale(). I am not sure about when I should scale my data, and whether the dependent variable should be scaled. If the dependent variable is scaled, how I give a prediction to the real data? I appreciate for any suggestions and comments. Best regards, Jinsong ===== (Mr.) Jinsong Zhao Ph.D.

Hi,all! I encountered a problem "not-yet-implemented method for <list> %*% <dgCMatrix>" when I tried "diagr %*% design_mat", where "diagr<-diag(vr,100)", vr is a vector with 100 elements, and design_mat is a sparse matrix with dimension 100*677000 constructed by calling sparseMatrix(). I am new to the Matrix package, so I am confused with this, and I

Dear all, I am a newcomer to R. I intend to using R to do stepwise regression and PLS with a data set (a 55x20 matrix, with one dependent and 19 independent variable). Based on the same data set, I have done the same work using SPSS and SAS. However, there is much difference between the results obtained by R and SPSS or SAS. In the case of stepwise, SPSS gave out a model with 4 independent
