reporter

Key Features

The reporter package contains the following key features:

• Titles, footnotes, page header, and page footer are repeated on each page
• Supports header labels and spanning headers
• Calculates default columns widths automatically
• Includes automatic wrapping and splitting of wide and long tables
• Integrates with the fmtr package to format numeric, date, and character data
• Plots from the popular ggplot2 package can be added to RTF, PDF, HTML, and DOCX reports
• Allows appending multiple tables to a report, multiple tables to a page, and intermingling of text, tables, and plots
• Supports in-report date/time stamps and “Page X of Y” page numbering

How to use reporter

There are four steps to creating a report:

• Create report content
• Create report
• Add content to the report
• Write out the report

You can create the report with the create_report() function. Content is created with the create_table(), create_text(), or create_plot() functions. Add content to the report with the add_content() function. Finally, the report can be written to a file with the write_report() function.

Let’s look at a simple example:

library(reporter)
library(magrittr)

# Create temp file name 
tmp <- file.path(tempdir(), "example.pdf")

# Create report content
tbl <- create_table(mtcars) %>% 
  titles("MTCARS Sample Data") %>% 
  footnotes("* Motor Trend, 1974")

# Create report and add content  
rpt <- create_report(tmp, output_type = "PDF", 
                     font = "Courier", font_size = 12) %>% 
  add_content(tbl)
  
# Write out the report
write_report(rpt)

# Un-comment to view report
# file.show(tmp)

As you can see, using the reporter package, you can create a useful report with just a few lines of code. By default, the package creates a text report. But you can create reports in RTF, PDF, HTML, and DOCX with just a single parameter change.

Besides the functions shown above, there are additional functions to create page headers and footers, spanning headers, a report stub, a by-variable, and more. The package also allows you to add text and plots to a report. All of these capabilities are demonstrated in the examples below.
