Dear Francois Vielle,
My name is Davide Chicco and I am a scientific associate researcher at the Peter Munk Cardiac Centre. I work on machine learning applied to health care, and I am especially
interested in sepsis prediction in patients.
I just discovered your aVirtualTwins project, and I downloaded the code and the dataset. The dataset looks very interesting to me, and I would like to know more about it.
Some questions:
1)) I just took a look at the features: "survival" "THERAPY"
"PRAPACHE" "AGE" "BLGCS" "ORGANNUM" "BLIL6" "BLLPLAT"
"BLLBILI" "BLLCREAT" "TIMFIRST" "BLADL" "blSOFA".
What is the meaning of these feature names?
Where can I find more information about them?
I found the description of these features in your thesis in French.
survival: 1 pour la survie au bout de 28 jours, 0 sinon
THERAPY: 1 pour le traitement actif, 0 pour le traitement de contrôle
TIMFIRST: Temps entre la prise de traitement et la défaillance du premier organe
AGE: Age du patient en années
BLLPLAT: Les plaquettes à baseline
blSOFA: Somme du sofa à baseline (score)
BLLCREAT: Créatinine à baseline
ORGANNUM: Nombre d'organes en défaillance à baseline
PRAPACHE: Score Pre-infusion Apache II
BLGCS: Echelle de Glasgow (état de conscience) à baseline
BLIL6: Concentration du serum IL-6 à baseline
BLADL: score Activity of daily
BLLBILI: Bilirubine à baseline
Can you please translate them into English please?
2)) What is the origin of this dataset?
Did you collect it from an hospital? Was it an online resource?
3)) Did you publish any scientific paper about this project?
If yes, can you please share it here?
Merci beaucoup, au revoir
-- Davide
Hi Prise6,
Thank you for creating this great R package aVirtualTwins.
I'm using it to do simulation to compare those subgroup identification methods.
I was wondering if there's a way for me to predict the subgroups of a test sample based on the subgroups I got from the training sample? I checked VT.predict(), it seems that's for the randomforest result not vt.tree()'s.
Thank you in advance!
Regards,
Luxi
CRAN wrote me with this issue to fix to maintain package :
From the 'NEWS' in R-devel
• R CMD check now also applies the settings of environment variables _R_CHECK_SUGGESTS_ONLY_ and _R_CHECK_DEPENDS_ONLY_ to the re-building of vignettes.
which enables more thorough checking of the manual's
All packages that are needed to successfully run R CMD check on the package must be listed in one of ‘Depends’ or ‘Suggests’ or ‘Imports’R_CHECK_SUGGESTS_ONLY=true is part of -as-cran: see your package's CRAN results page (which will still be updating for this change).
The missing packages need to be declared in the Suggests: field -- there may be others missing since vignette re-building stops at the first error. You can confirm all needed packages used are declared by using 'R CMD check --as-cran' with current R-devel.
Where alternative vignette builders are used, some packages may also need to be declared in the VignetteBuilder: field:
The ‘VignetteBuilder’ field names (in a comma-separated list) packages that provide an engine for building vignettes. These may include the current package, or ones listed in ‘Depends’, ‘Suggests’ or ‘Imports’. The utils package is always implicitly appended. See Non-Sweave vignettes for details. Note that if, for example, the vignette ‘engine’ is ‘knitr::rmarkdown’ this field needs to declare both knitr and rmarkdown.This includes any additional packages needed by the vignette builders (e.g. formatR, webshot).
