php7 RSQLite is the easiest way to use a database from R because the package itself. You can do this either by subsetting mycounts with as.matrix(mycounts), or by tweaking your call to read.table() as showed by Nico. If table column is VARCHAR and has all the numeric values in it. MATLAB is a programming and numeric computing platform used by millions of engineers and scientists to analyze data, develop algorithms, and create models. To get an integer matrix, you first need to get rid of this column. Basic data types in R can be divided into the following types: numeric - (10. As Nico said, that's because one of the columns (the 1st one) in your ame is of type character (or factor). Calling as.matrix() on your mycounts ame should work except that it will turn it into a character matrix, not an integer matrix.Note that calling as.integer() on a list only works in the very particular case where all the list elements have a length <= 1. A ame is a special kind of list hence the error message you got. The numeric () method takes a non-negative integer defining the desired length. It creates a double-precision vector of the defined length with each item equal to 0. The table below shows all the Arithmetic Operators in R Programming language with examples. All these R arithmetic operators are binary operators, which means they operate on two operands. The numeric () function is identical to double () method. The R Arithmetic operators include operators like Arithmetic Addition, Subtraction, Division, Multiplication, Exponent, Integer Division, and Modulus. It could be that you got the error message you show us by calling as.integer() on the mycounts ame. The is.numeric () in R is a built-in function that checks if the object can be interpretable as numbers or not.However, your mycounts object is a ame, not an integer vector. a character vector (say, vec) are mostly numeric, with a few non-numeric items that we are prepared to convert to NA. To convert an integer vector to a numeric vector, just call as.numeric() on it.

> User wrote Question: converting integer to numeric: > Activity on a post you are following on To get a matrix out of your example, do this instead: coerce it as a matrix using as.matrix(mycounts) you will get the error you see, because of the different datatypes in your ame.Īs you have not included all the commands you ran, including the one generating the error in your post, it is hard to guess what might have triggered it. At the moment, your mycounts object is a ame mixing both characters (the first column) and integer/numeric values (your second to fourth columns).ĭepending on what you want to do with your object, e.g.
