Re: [R] nested for loop with data table

Hi Ek, I think you want your example to look like this: Sample<-read.table(text= "Num Color Grade Value Month Day 1 yellow A 20 May 1 2 green B 25 June 2 3 green A 10 April 3 4 black A 17 August 3 5 red C 5 December 5 6 orange D 0 January 13 7 orange E 12 January 5 8 orange F 11 February 8 9

Re: [R] nested for loop with data table

There's a lot that doesn't make sense here. I think what you need to do is produce a small, reproducible example, post that with dput() and state your question more clearly - including what you have tried and what didn't work. You'll probably be amazed how quickly you will get good advice if

[R] nested for loop with data table

I have a huge data file; a sample is listed below. I am using the package data table to process the file and I am stuck on one issue and need some feedback. I used fread to create a data table. Then I divided the data table (named File1) into 10 general subsets using common table commands such as:

Re: [R] clip a raster according to a shape file in R.

The answer is yes. However there are quite a few online resources (including blogs and the CRAN Spatial Task View and vignettes for packages mentioned there) that describe various tools and step you through how to do this, and you have not provided a reproducible example, and there is a whole

Look more carefully at y. If this is a factor, please note what is the first (reference) level and what the second. This determines the rule, not the value of the first observation. Best, Uwe Ligges On 02.05.2017 07:25, Daniel Jeske wrote: Hello - I have noticed that when I run svm() the

[R] Unusual behavior in e1071?

Hello - I have noticed that when I run svm() the order of my data matters. If the first case in the data frame has y=+1 I get the expected decision rule that says to classify as +1 if f(x)>0. However, if the first case in the data frame has y=-1 then apparently the decision rule being used says

[R] clip a raster according to a shape file in R.

I have a grid data which has values of a variable (e.g: Temperature). My data has 6069 data points where each data point refers to different latitude and longitude. I want to transform this data to a raster file so that I can clip it according to a shapefile that has much smaller boundaries than
