In this video, Mark Niemann-Ross demonstrates working with tab-delimited files in R. Learn how to effectively import and export tab-delimited files with base R and the tidyverse using read.table and read_table.
- [Instructor] Tab-delimited files…are another common format for data interchange.…Each field in the file is separated by a tab character.…Let's look at how to import that into R.…First, I've created a vector called sampleTDF,…which contains the path name to a tab-delimited file…called LPO weather dot tdf.…Now, reading this is fairly simple.…I'm going to create a vector…that I'm going to read this data into.…We'll call it readTableTDF…and into that I'm going to use…the read dot table command from base R…sampleTDF, which is the vector to the file name…and I hit return and you can see that…I now have in the upper right hand corner…a readTableTDF of 100 observations of nine variables…and we can take a quick look at what that looks like.…
So what we're looking at is exactly what you might expect.…Well, almost.…I'll draw your attention to the names of…the columns V1, V2, V3, V4.…The first row is actually what should be…the names of the columns.…So we need to tell readTable to use…the first line as a header and we can do that by typing in…
