similar to: Interpolating hourly basis

 Good Morning , I want to sample the following time series for every third hour. For example at 00:00,03:00,06:00,09:00 etc.                     2011-01-01 00:00:00 0.000000e+00 2011-01-01 01:00:00 1.471667e+01 2011-01-01 02:00:00 1.576667e+01 2011-01-01 03:00:00 0.000000e+00 2011-01-01 04:00:00 0.000000e+00 2011-01-01 05:00:00 0.000000e+00 2011-01-01 06:00:00 0.000000e+00 2011-01-01 07:00:00

Hi, I'm trying to generate valid R code using R. Parts of the task is to read a sequence of characters from file and escape them such that they can be put in quotation marks to form a valid R code string. Example: Let the input file be (four rows containing ASCII 0-255 characters): abcdef<tab>ghijk\nlmno second row\t\a\\ fourth and so on... <EOF> Now, find escapeString() such

I''m attempting to store a value that''s dependent on an environment variable in a custom .yml file, like so: job_folder: "#{RAILS_ROOT}/jobs" Doesn''t seem to like that. Is there any way for me to have access to the RAILS_ROOT environment variable from inside of my configuration file? Thanks, Wes -- Posted via http://www.ruby-forum.com/.

Greetings R Users, I?m new to R but at least managed to read in multiple files: filenames <- list.files(path=getwd()) numfiles <- length(filenames) for (all_temp in c(1:numfiles)) { filenames[all_temp] <- paste(filenames[all_temp],sep="") assign(gsub("[.]ASC$","temp",filenames[all_temp]),read.delim2(filenames[all_temp],

Hi everyone I was using spline to interpolate single or two consecutive missing data points in time series. However, when it comes to longer gaps in the data the spline function generate new data for both my known and unknown data (see below). Aside from not understanding why this happens, I thought thought I might try function "aspline" in library (akima). However, I cannot install or

I have a big dataset containing a lot of values for 1970, 1980 and 1990. I want to interpolate values for the years in between, and also if possible to extrapolate to 1968 and 1969. The method doesn't have to be clever but I am looking for a function that will do all the data at once. (Doing foreach, or apply, is just too slow!) Is there something that will take list(df$val.1970, df$val.1980,

Hi Guys I am trying to read a bunch of files in the loop but pipe function which I use to cut few columns is somehow unable to interpolate the file variable. eg: > file="check.txt" > data <- read.table(pipe("cut -f 2,3 file"), sep="\t", col.names=c('pos','cov') ) cut: file: No such file or directory how can I pass variable file to pipe

The purpose of this email is to ask for pre-built procedures or techniques for smoothing and interpolating missing time series data. I've made some headway on my problem in my spare time. I started with an irregular time series with lots of missing data. It even had duplicated data. Thanks to zoo, I've cleaned that up -- now I have a regular time series with lots of NA's.

I have a time series for two variables measured simultaneously, but at different intervals. The variables are not independent, so the patterns in the times series are very similar (one variable goes up when the other goes up, etc). For example, let's pretend my data look something like this (but with more noise)... var1_times<-c(0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10) var1_values<-c(0,

Hello I am new to R and am coming from a Perl background. I have had trouble figuring out from the documentation how to interpolate a variable into a quoted string (if it's possible). This seems to be necessary when writing a script that must print out strings (for example plot legends) whose content is calculated during the execution of the script. In perl I could write: $name =

#I would like to interpolate a straight line between 06/08/06 04:16:00 - 06/08/06 20:31:00 with values and then sum them. This is an estimate of ecosystem #respiration and I will be using this in a larger context(48 days of these diurnal curves), but for right now I am just trying to figure out how to do it for this one #day example. I have some other code for Ecosystem (stream) Metabolism that

Hi everyone, I am desperately looking for a method to interpolate strings within an SQL statement as follows: I get a lot of rows out of a database (in my example POSITION_to_ZIPCODE Database with holds records for German ZIP Code <--> Gauss-Krueger Coordinate System ) and want this to be selected and computed individually row by row as follows: library(RODBC) channel <-

is there a way to use the actual index value for plotting zoo objects this is the way that the index is set up and a sample range of what I would like to plot 01/01/06 00:00:00 - 01/01/06 23:45:00 { library(zoo) # chron library(chron) fmt.chron <- function(x) { chron(sub(" .*", "", x), gsub(".* (.*)", "\\1:00", x)) }} x <- structure(c(15.57, 15.5,

Hi Hemant, As I suspected, the code broke when I got to the line: result <- rfm_auto(df, id="user_id", payment ="subtotal_amount", date="created_at") Error in rfm_auto(df, id = "user_id", payment = "subtotal_amount", date = "cr eated_at") : could not find function "rfm_auto" It looks like you are using the hoxo-m/easyRFM

I'm trying to perform an RFM analysis on the attached dataset, I'm able to get the results using the auto_rfm function but i want to define my own breaks for RFM. as follow r <-c(30,60,90) f <-c(2,5,8) m <-c(10,20,30) but when i tried to define my own breaks i got the identical result for RFM i.e 111 for every ID. please help me with this with working R script so that i can get

Hi 2 all ! I have problems with concurrent filesystem actions on a ocfs2 filesystem which is mounted by 2 nodes. OS=RH5ES and OCFS2=1.2.6 F.e.: If I have a LV called testlv which is mounted on /mnt on both servers and I do a "dd if=/dev/zero of=/mnt/test.a bs=1024 count=1000000" on server 1 and do at the same time a du -hs /mnt/test.a it takes about 5 seconds for du -hs to execute: 270M

hi all, I want to move some routing tasks out of the router and into the controller. The goal is to make Merb feel less like mod_rewrite and give the user more control at the controller. The new Router is simple: it takes the path_info (not the whole request) then outputs a controller class and some parameters from the path matching. The rest of the routing would be done at the controller level.
