[R] How to threshold point in time series

Hi All, I am having very high-frequency data, captured between 3 to 7 seconds by sensor for liquid tank and capacity of tank is 50k dm3. When tank capacity reduce to 1k dm3, than tank refilling need to call. How in time series we can perform, refilling can call when tank capacity reduce to 1k dm3,

[R] Calculating AIC and BIC for Time Series Models

Dear friends, I have been fitting some TS models from the forecast package like ets(), ses(), hw(), HoltWinters(), stlf(), bats() and tbats(), however, when trying to use the AIC and BIC functions, I receive the following error message: Error in UseMethod("logLik") : no applicable method for 'l

Re: [R] Calculate focal values for neighboring cells that are located at the raster edge from the function "focal" in the R package "raster"

The r-sig-geo list is often a better place to post for such "geographically" related questions, especially if you don't get a helpful response here. But R is open source, so typing raster:::focal at the command line prompt will show you the function code if it is written in R. Whether that is

[R] Calculate focal values for neighboring cells that are located at the raster edge from the function "focal" in the R package "raster"

Hello All, I am using the function "focal" in the R package "raster" but I don�t understand how the function calculates values for neighboring cells that are located at the raster edge. Here is an example reproducible: f <- matrix(1, nrow=3, ncol=3) f[c(1,3,7,9)]=1/sqrt(2) f[5]=0 func <- funct

Re: [R] open help files from Terminal

While we are on the topic, if you wanted to go the other way (open help in terminal without a whole R session) you can do R --no-init-file --slave -e "?sd" I suspect this does start an R session in the background, but makes for a clean way to view docs through terminal if you use an alias. Cheer

Hi, if you are willing to use dplyr, you can do all in one line of code: library(dplyr) df<-data.frame(id=1:10,A=c(123,345,123,678,345,123,789,345,123,789)) df%>%group_by(unique_A=A)%>%summarise(list_id=paste(id,collapse=", "))->r cheers Am 06.06.2018 um 10:13 schrieb Massimo Bressan: > #given
