These functions can be used to predefine your own reference to be used in \code{\link[=as.mo]{as.mo()}} and consequently all \verb{mo_*} functions like \code{\link[=mo_genus]{mo_genus()}} and \code{\link[=mo_gramstain]{mo_gramstain()}}.
|
|
|
|
This is \strong{the fastest way} to have your organisation (or analysis) specific codes picked up and translated by this package.
|
|
}

|
The reference file can be a text file seperated with commas (CSV) or tabs or pipes, an Excel file (either 'xls' or 'xlsx' format) or an R object file (extension '.rds'). To use an Excel file, you need to have the \code{readxl} package installed.
|
|
|
|
\code{\link[=set_mo_source]{set_mo_source()}} will check the file for validity: it must be a \code{\link{data.frame}}, must have a column named \code{"mo"} which contains values from \code{\link[=microorganisms]{microorganisms$mo}} and must have a reference column with your own defined values. If all tests pass, \code{\link[=set_mo_source]{set_mo_source()}} will read the file into R and export it to \code{"~/.mo_source.rds"}. This compressed data file will then be used at default for MO determination (function \code{\link[=as.mo]{as.mo()}} and consequently all \verb{mo_*} functions like \code{\link[=mo_genus]{mo_genus()}} and \code{\link[=mo_gramstain]{mo_gramstain()}}). The location of the original file will be saved as option with \code{options(mo_source = path)}. Its timestamp will be saved with \code{options(mo_source_datetime = ...)}.
|
|
|
|
\code{\link[=get_mo_source]{get_mo_source()}} will return the data set by reading \code{"~/.mo_source.rds"} with \code{\link[=readRDS]{readRDS()}}. If the original file has changed (the file defined with \code{path}), it will call \code{\link[=set_mo_source]{set_mo_source()}} to update the data file automatically.
|
|
|
|
Reading an Excel file (\code{.xlsx}) with only one row has a size of 8-9 kB. The compressed file used by this package will have a size of 0.1 kB and can be read by \code{\link[=get_mo_source]{get_mo_source()}} in only a couple of microseconds (a millionth of a second).
|
|
\subsection{How it works}{
|
|
|
|
Imagine this data on a sheet of an Excel file (mo codes were looked up in the \code{microorganisms} data set). The first column contains the organisation specific codes, the second column contains an MO code from this package:\preformatted{ | A | B |
|
|
--|--------------------|--------------|
|
|
1 | Organisation XYZ | mo |
|
|
2 | lab_mo_ecoli | B_ESCHR_COLI |
|
|
3 | lab_mo_kpneumoniae | B_KLBSL_PNMN |
|
|
4 | | |
|
|
}
|
|
|
|
We save it as \code{"home/me/ourcodes.xlsx"}. Now we have to set it as a source:\preformatted{set_mo_source("home/me/ourcodes.xlsx")
|
|
# Created mo_source file '~/.mo_source.rds' from 'home/me/ourcodes.xlsx'.
|
|
}
|
|
|
|
It has now created a file \code{"~/.mo_source.rds"} with the contents of our Excel file, but only the first column with foreign values and the 'mo' column will be kept.
|
|
|
|
And now we can use it in our functions:\preformatted{as.mo("lab_mo_ecoli")
|
|
[1] B_ESCHR_COLI
|
|
|
|
mo_genus("lab_mo_kpneumoniae")
|
|
[1] "Klebsiella"
|
|
|
|
# other input values still work too
|
|
as.mo(c("Escherichia coli", "E. coli", "lab_mo_ecoli"))
|
|
[1] B_ESCHR_COLI B_ESCHR_COLI B_ESCHR_COLI
|
|
}
|
|
|
|
If we edit the Excel file to, let's say, by adding row 4 like this:\preformatted{ | A | B |
|
|
--|--------------------|--------------|
|
|
1 | Organisation XYZ | mo |
|
|
2 | lab_mo_ecoli | B_ESCHR_COLI |
|
|
3 | lab_mo_kpneumoniae | B_KLBSL_PNMN |
|
|
4 | lab_Staph_aureus | B_STPHY_AURS |
|
|
5 | | |
|
|
}
|
|
|
|
...any new usage of an MO function in this package will update your data file:\preformatted{as.mo("lab_mo_ecoli")
|
|
# Updated mo_source file '~/.mo_source.rds' from 'home/me/ourcodes.xlsx'.
|
|
[1] B_ESCHR_COLI
|
|
|
|
mo_genus("lab_Staph_aureus")
|
|
[1] "Staphylococcus"
|
|
}
|
|
|
|
To remove the reference data file completely, just use \code{""} or \code{NULL} as input for \verb{[set_mo_source()]}:\preformatted{set_mo_source(NULL)
|
|
# Removed mo_source file '~/.mo_source.rds'.
|
|
}
|
|
}
|
|
}
|
|
\section{Stable lifecycle}{
|
|
|
|
\if{html}{\figure{lifecycle_stable.svg}{options: style=margin-bottom:5px} \cr}
|
|
The \link[AMR:lifecycle]{lifecycle} of this function is \strong{stable}. In a stable function, we are largely happy with the unlying code, and major changes are unlikely. This means that the unlying code will generally evolve by adding new arguments; we will avoid removing arguments or changing the meaning of existing arguments.
|
|
|
|
If the unlying code needs breaking changes, they will occur gradually. To begin with, the function or argument will be deprecated; it will continue to work but will emit an message informing you of the change. Next, typically after at least one newly released version on CRAN, the message will be transformed to an error.
