Combining csv files in R to different columns : <p>I have over 100 csv files, each containing one column of Date and Time (which are the exact same values for every file) and then a second column that is different for every file. I want the file name to be the column name. </p>

<p>So essentially I want to add a column to my data frame for each file.</p>

<p>What's the most efficient way to do this?</p>

<p>So far all I've done is make a list of all of the csv files in my folder because all of the information I have found so far only seems to be telling me how to add the data as more rows, not more columns.</p>
