[R] Selecting rows and columns of a data frame using relational operators

Consider a data frame named data. data contains 4 columns and 1000 rows. Say the aim is to bring together columns 1, 2, and 4, if the values in column 4 is equal to 1. We could use the syntax data(data[,4] == 1, c(1 2 4)) for this purpose. Suppose now that the aim is to bring together columns 1,

Re: [R] Selecting rows and columns of a data frame using relational operators

The answer is simple data[,4] == 1 produces a logical vector of length nrow(data) and the subsetting mechanism for data frames in R needs a vector of the same length as the data frame has rows. data[1:20,4] == 1 produces a data frame of length 20, and if this is not the length of data. So R

Re: [R] How to prune using a validation set

You will need to give more detail of exactly what you mean by "prune using a validation set". THe prune.rpart function will prune at any value you want, what I suspect you are looking for is to compute the error of each possible tree, using a validation data set, then find the best one, and

Re: [R] Selecting rows and columns of a data frame using relational operators

Hi Tunga, The function subset() is probably what you are looking for. You might also want to look at a tutorial to understand the R syntax. In addition, calling your data data is not a good idea because of the name clash with the function data(). Hope this helps, Ulrik On Mon, 27 Feb 2017 at

[R] concurvity

Hi, I'm using the concurvity function to check for concurvity in my model. The output I get when comparing to the rest of the model (ie full=TRUE) many of the variables have concurvity values higher than 0.9. However when comparing the terms pairwise most values are very small, less than 0.1

nb() will default to "REML" smoothing parameter estimation, while negbin() will default to "UBRE" unless you use the 'method="REML"' option to 'gam'. Using UBRE in place of REML may lead to differences in model fit, and will also mean that the AIC is not corrected for smoothing parameter
