MadsR - let's get to the fun part.

MadsR is a package designed for my own uses with data from the danish microbiological system MADS.

Installation

devtools::install_github("marcmtk/MadsR")

Functions implemented

This package provides 6 functions to assist with epidemiological analyses of MADS data and 2 functions to generate MADS like data for testing purposes.

Examples

Consider the dataset provided in analyser-like.csv with read_csv vs read_mads

df <- read.csv("./extdata/analyser-like.csv")
str(df)

## 'data.frame':    1000 obs. of  7 variables:

Let's filter some cases and look at the results

cases <- filter_cases(df, result=="Positiv", min.days.to.new.episode=14)
table(cases$hosp_afd, cases$episode)

##      
##        1  2  3

table(cases$sl)

## 
##  15  17  53  95 124 144 306 315 343 369 437 470 530 534 598 
##   1   1   1   1   1   1   1   1   1   1   1   1   1   1   1

Now let's look at a since last plot, after all there may be an epidemic out there!

since_last(df) %>% slplot()

since_last(df) %>% filter(hosp_afd=="S V") %>% slplot()

filter(df, hosp_afd == "S V") %>% since_last() %>% slplot()

Note the difference between plot 2 and plot 3. It is very important that time since last positive case is computed after relevant filtering.

Last useful functions, tallying by department and heatmapping the results:1

tbd <- tally_by_department(df, "patient", result == "Positiv")

## Joining by: c("hosp_afd", "year", "month")
## Joining by: c("hosp_afd", "year", "month")

tally_map(tbd)

filter(tbd, hosp_afd != "AP ") %>% tally_map
