* Possibility to globally set the default for the amount of items to print, with `options(max.print.freq = n)` where *n* is your preset value
|
||||
|
||||
#### Changed
|
||||
* Updates version of the `setic_patients` dataset to better reflect the reality
|
||||
* Improvements for forcasting with `resistance_predict` and added more examples
|
||||
* More antibiotics for EUCAST rules
|
||||
* Updated version of the `setic_patients` data set to better reflect the reality
|
||||
* Pretty printing for tibbles removed as it is not really the scope of this package
|
||||
* Improved speed of key antibiotics comparison for determining first isolates
|
||||
* Column names for the `key_antibiotics` function are now generic: 6 for broadspectrum ABs, 6 for Gram-positive specific and 6 for Gram-negative specific ABs
