Keep rows that match a condition. Source: R/filter.R. The filter () function is used to subset a data frame, retaining all rows that satisfy your conditions. To be retained, the row must produce a value of TRUE for all conditions. Note that when a condition evaluates to NA the row will be dropped, unlike base subsetting with [.> r <- 0:10 * 2 > r [1] 0 2 4 6 8 10 12 14 16 18 20 Share. Improve this answer.

The default method "glm.fit" uses iteratively reweighted least squares (IWLS): the alternative "model.frame" returns the model frame and does no fitting. Note that in R < 4.1.0, factors were treated only via their internal integer codes: now there is c.factor method which combines factors into a factor. c is sometimes used for its side effect of removing attributes except names, for example to turn an array into a vector. as.vector is a more intuitive way to do this, but also drops names.

"mfrow" might be thought of as matrix-frame-by-row, since the ...

Creating a matrix in R is quite simple, it involves the Matrix function that has the format of matrix (vector, ncol=columes, nrow=rows2) and it takes the vector and converts it to specified number of rows and columns. Now, the number of rows multiplied by the number of columns must equal the total number of elements in the vector.

The difference in assignment operators is clearer when you use them to set an argument value in a function call. For example: median(x = 1:10) x. ## Error: object 'x' not found. In this case, x is declared within the scope of the function, so it does not exist in the user workspace. median(x <- 1:10) x. An Introduction to the c () Function in R. You can use the c () function in R to perform three common tasks: 1. Create a vector. 2. Concatenate multiple vectors. 3. …A few problems: there is not a strict equivalence between c and being a vector; a vector is not at all like a collection, in the mathematical sense; data.frames have accessors that align perfectly with intuition from matrix algebra (try a[1,] and a[1,1] for your examples).a[1] and a[[1]] are additional accessors that no one promised would align with matrix algebra; nor …Occasionally you may want to re-order the levels of some factor variable in R.
