**R Vectors**

To generate numbers from a normal distribution, use rnorm(). By default the mean is 0 and the standard deviation is 1.... Suppose for example, you wished to interleave the elements of a1 and a2, but that a1 has one more element than does a2. So now the first and last elements in your result vector will come from a1.

**How can I repeat each element of a vector different times**

How can I repeat each element of a vector different times and store them in a new vector... A vector is a sequence of data elements of the same basic type. Members in a vector are officially called components . Nevertheless, we will just call them members in this site.

**R Apply a Function over a List or Vector stat.ethz.ch**

Explain what a for loop does. Correctly write for loops to repeat simple calculations. Trace changes to a loop variable as the loop runs. Trace changes to other variables as they are updated by a for loop. Use a function to get a list of filenames that match a simple pattern. Use a for loop to... Today I worked on a simulation program which require me to create a matrix by repeating the vector n times (both by row and by col). Even the task is extremely simple and only take 1 line to finish(10sec), I have to think about should the argument in rep be each or times and should the argument in

**R Vectors**

The “<-” tells R to take the number to the right of the symbol and store it in a variable whose name is given on the left. You can also use the “=” symbol.... Merge two vectors into one. Dear R users, Given two vectors x and y a=1 2 3 b=4 5 6 i want to combine them into a single vector z as 1 4 2 5 3 6 Thanks for your help Tham Dear R users, Given two vectors x and y a=1 2 3 b=4 5 6 i want to combine them into a single vector z as 1 …

## R How To Repeat 0 And Store N Vector

### A very common question among new MATLAB users is how to store the results of a calculation done in a for loop. I covered how to do this when the result is a scalar However, I did not cover how to do this if you are creating a vector each time through the loop.

- Apply a Function over a List or Vector Description. lapply returns a list of the same length as X, each element of which is the result of applying FUN to the corresponding element of X.
- Split the elements of a character vector x into substrings according to the matches to substring split within them. A missing value of split does not split the corresponding element(s) of x at all. The algorithm applied to each input string is repeat { if the string is empty break. if there is a
- R for Loop. Loops are used in programming to repeat a specific block of code. In this article, you will learn to create a for loop in R programming. A for loop is used to iterate over a vector in R programming. Syntax of for loop for (val in sequence) { statement } Here, sequence is a vector and val takes on each of its value during the loop. In each iteration, statement is evaluated
- x: either a vector of one or more elements from which to choose, or a positive integer. See ‘Details.’ n: a positive number, the number of items to choose from.
