How to download subset of file created in r

Subsetting a data frame consists on obtaining some rows or columns of the full data frame, or some that meet one or several conditions. It is very usual to subset a data frame in R for analysis purposes. Consider, for instance, the following sample data frame:. You can also subset a data frame depending on the values of the columns.

As an example, you may want to make a subset with all values of the data frame where the corresponding value of the column z is greater than 5, or where the group of the w column is Group 1. You can also apply a conditional subset by column values with the subset function as follows.

Note that when using this function you can use the variable names directly. When using the subset function with a data frame you can also specify the columns you want to be returned , indicating them in the select argument.

In adition, you can use multiple subset conditions at once. Subsetting with multiple conditions is just easy as subsetting by one condition. In the following example we select the values of the column x , where the value is 1 or where it is 6. Analogously to column subset, you can subset rows of a data frame indicating the indices you want to subset as the first argument between square brackets.

Many data frames have a column of dates. In the previous example, we have downloaded a csv file. Furthermore, it is possible to download files from a sharepoint or a web application such as shiny. Do you need further guidance for the downloading of files from the web? The video does not only show another example for the application of the download. It also explains how to import this data to R or RStudio.
