[R] max and in the zoo package
hi everyone. i am dealing on a zoo-class object.i am aware of the 'min' and 'max' function to get the minimum and the maximum values.getting these maximum and minimum values is ont thing.but, how to get the (zoo) dates these values occur ? in fact, in analysing a time series i am interested in the particular (extreme) values AND in the moments they happen. regards.edouard.

[R] ADF test : how to deal with the missing values ?
hi everyone, and happy new year. i want to perform an Augmented Dickey Fuller test. the basic adf.test function doesn't work on my dataset as data are missing. has a package a function enabling missing values ? does any one know a trick to get through ? thanks, édouard. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
[R] how to create a simple loop ?
I have a 5-row matrix called âdataâ. There are headers. it look like this : Row 1 Row2Row3Row4Row5 Line1 â¦â¦â¦â¦ Line2 â¦â¦â¦â¦ Line3 â¦â¦â¦â¦ ⦠Line 1838 â¦â¦â¦â¦ I want to calculate several simple arithmetic means for Row5, that is from Line173 to Line193, from Line434 to Line455, from Line699 to Line724, from Line955 to Line977 A simple way is to individually compute these means. The first one (Line173 to Line193) is then obtained by : mean(data[173:193,5], na.rm = TRUE) Thatâs right ! But, I aim to automate this calculation by creating a loop. I tried many things, but I have been unsuccessful at using the âforâ loop function. Please, donât explain things too hard as it is often the case that people wants to help but gets into too much sophistication. Someone can write that little code for this example ? Or suggest functions ? Thanks for your help. Cheers, Ãdouard.
