visOmopResults offers a set of functions tailored to
format objects of class <summarised_result> (as
defined in omopgenerics
package).
It provides functionality to: transform data, create table visualizations, and generate plot visualizations. These visualizations are highly versatile for reporting results through Shiny apps, RMarkdown, Quarto, and more, supporting various output formats such as HTML, PNG, Word, and PDF.
You can install the latest version of visOmopResults from CRAN:
install.packages("visOmopResults")Or you can install the development version from GitHub with:
# install.packages("pak")
pak::pkg_install("darwin-eu/visOmopResults")The <summarised_result> is a standardised output
format utilized across various packages, including:
Although this standard output format is essential, it can sometimes be challenging to manage. The visOmopResults package aims to simplify this process. To demonstrate the package’s functionality, let’s start by using some mock result:
library(visOmopResults)
result <- mockSummarisedResult()<summarised_result> objectA tidy version of the summarised can be obtained with the tidy function:
tidy(result)
#> # A tibble: 72 × 13
#> cdm_name cohort_name age_group sex variable_name variable_level count
#> <chr> <chr> <chr> <chr> <chr> <chr> <int>
#> 1 mock cohort1 overall overall number subjects <NA> 8073003
#> 2 mock cohort1 <40 Male number subjects <NA> 8850788
#> 3 mock cohort1 >=40 Male number subjects <NA> 3811096
#> 4 mock cohort1 <40 Female number subjects <NA> 7230087
#> 5 mock cohort1 >=40 Female number subjects <NA> 6508723
#> 6 mock cohort1 overall Male number subjects <NA> 7643684
#> 7 mock cohort1 overall Female number subjects <NA> 4209114
#> 8 mock cohort1 <40 overall number subjects <NA> 5850048
#> 9 mock cohort1 >=40 overall number subjects <NA> 8239237
#> 10 mock cohort2 overall overall number subjects <NA> 7597918
#> # ℹ 62 more rows
#> # ℹ 6 more variables: mean <dbl>, sd <dbl>, percentage <dbl>,
#> # result_type <chr>, package_name <chr>, package_version <chr>This tidy format is no longer standardized but offers easier
manipulation. While tidy() provides a straightforward
transformation, the more customizable sibling function
tidySummarisedResult() allows you to specify exactly how
you’d like to tidy your <summarised_result>
object:
result |>
tidySummarisedResult(
splitStrata = FALSE,
settingsColumns = "package_name",
pivotEstimatesBy = NULL
)

#> # estimate_type <chr>, estimate_value <chr>, package_name <chr><summarised_result> objectA <summarised_result> object is essentially a
<data.frame>, so it can be filtered easily using
dplyr::filter(). However, filtering variables within
name-level structures or those present in the settings can be
challenging. The following functions simplify this process:
filterSettings()filterGroup()filterStrata()filterAdditional()Here are some examples on how to use them:

#> # estimate_name <chr>, estimate_type <chr>, estimate_value <chr>,
#> # additional_name <chr>, additional_level <chr>Currently all table functionalities are built around 3 packages: tibble, gt, and flextable.
There are two main functions:
visOmopTable(): Creates a well-formatted table
specifically from a <summarised_result> object.visTable(): Creates a nicely formatted table from any
<data.frame> object.Let’s see a simple example:
result |>
visOmopTable(
type = "flextable", # to change to gt when issue 223 is fixed
estimateName = c(
"N(%)" = "<count> (<percentage>%)",
"N" = "<count>",
"mean (sd)" = "<mean> (<sd>)"),
header = c("sex"),
settingsColumns = NULL,
groupColumn = c("cohort_name", "age_group"),
rename = c("Variable" = "variable_name", " " = "variable_level"),
hide = "cdm_name"
)
Currently all plot functionalities are built around ggplot2. The
output of these plot functions is a <ggplot2> object
that can be further customised.
There are three plotting functions:
plotScatter() to create a scatter plot.plotBar() to create a bar plot.plotBox() to create a box plot.Let’s see how we can create a simple boxplot for age using this tool:
library(dplyr)
result |>
filter(variable_name == "number subjects") |>
filterStrata(sex != "overall") |>
barPlot(x = "age_group",
y = "count",
facet = "cohort_name",
colour = "sex")
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
