The first thing I have learned in R is how to load a table. Usually, when you start your R journey, someone more knowledgeable will tell you how to do this very first action. It will typically be:
You probably will be adding various parameters into the brackets such as “
row.names=0” or “
header=TRUE” or, “
sep="\t"“, to make sure you are reading your file correctly.
And this is perfectly fine, as a loading method of small datasets.
However, to maximize your time, let’s go over the common problems and, more importantly, their solutions new users can encounter when loading a dataset into R.
Problem #1: All the data is loaded into one column
Solution: This is fairly common. You need to specify the separator!
This can be achieved by adding sep=”XXX” into the read.table() function. In the place of XXX, you will put in your separator. Typically, it can be either the semi-column character (;) or a comma (,)
