After that, we can export R into different file formats for our further processing. CSV is one of popular format with which we want to come in this tutorial. 1. Write CSV in R. we can use R base functions to write CSV file without installing any other packages. 1.1. Write CSV in R using write.csv() function.
Working with data in a matrix Loading data. Our example data is quality measurements (particle size) on PVC plastic production, using eight different resin batches, and three different machine operators. The data set is stored in comma-separated value (CSV) format. Each row is a resin batch, and each column is an operator. In RStudio, open pvc.csv and have a look at what it contains. read.csv.

(You should save the file on your computer.) It is a good idea to open this file in a spreadsheet and look at it. This will help you make sense of how R stores the data.
I've extracted a feature vector from text files using CountVectorizer. Per file, it outputs a sparse matrix which I save into one CSV file. This is how I got the sparse matrix.
The defaults were changed to use compressed saves for save in 2.3.0 and for save.image in 2.4.0. Any recent version of R can read compressed save files, and a compressed file can be uncompressed (by gzip -d) for use with very old versions of R. See Also. dput, dump, load, data. Examples.
