Got it completely backwards the first time I tried it. Here I insert some text into an RMarkdown document. Alternatively, cat ('nnpagebreakn') can be used within an R script. pagebreak can be used the whitespace of an RMarkdown document. For me, it was confusing that I had to not escape the html columns. genius level - the cleanest and simplest solution Ive seen yet. This applies to other html as well including color. The links are made with html and must not be escaped to show up. This is done through not escaping content in the table, specifically the column with the links. Provide a list of other packages that produce tables. Highlight more advanced customization of tables using the kableExtra package ( Zhu 2021). For example: a data frame of variants w/ links to their position in a genome browser. This chapter aims to do the following: Show all features of the table-generating function knitr::kable (). Say you made a data frame with links you want to work in your html report. The kableExtra package () is designed to extend the basic functionality of tables produced using knitr::kable() (see Section 10.1). However, when I do so, the code from booktabs() appears in my LaTex document, even when I set the chuck option to echoFALSE. I would like to use the booktabs() option to include a horizontal rule. If one clicks “copy”, the table will be copied to your clipboard, “CSV” or “PDF” will save the table to the give file type, and “print” will bring put the table into a print friendly format and will bring up the print dialog box. I am using the tabular() function in the tables package to make tables in an R Markdown file. The above code adds “buttons” to the top of the table like so: The table “remembers” what you’ve changed so far-so if you sort by Sepal Length, filter pedal width to > 1 and select species “versicolor” the copied/saved table will have these same restrictions.īuttons = c('copy', 'csv', 'excel', 'pdf', 'print')) This enables users to copy the table, save as a csv, excel or PDF file, or print the table. Numeric columns have sliders Columns of class factor have a drop down menu Export DataĪnother useful aspect of the datatable function is the “Buttons” extension. One must add the filter = "top" (or bottom, etc.) to the code to enable this feature. The datatable function also allows users to filter each column depending on the datatype: filter numeric columns with a slider & filter columns of class factor with a drop down menu. Notice that to the right of each column name are two arrows: One may sort by ascending or descending order and the direction of the blue arrow indicates by which direction you sorted the column. Note at the bottom of the table it shows you how many entries (rows) were found and are being displayed. The widget also includes a search bar on the top right corner which can be very useful when interactively exploring data. One may select the number of entries to show by using the drop down menu like so: SEARCH BAR The default is 10, but I specified 5 as default with the code pageLength=5. You’ll notice that there is a drop down menu that says: “Show 5 entries”. This is a JavaScript based table, stored in a HTML widget, so a flat image doesn’t convey all of the interactive features. Already, the readability is much better than the base r function print.
