MultiDataSet: an R package for encapsulating multiple data sets with application to omic data integration
BACKGROUND: Reduction in the cost of genomic assays has
generated large amounts of biomedical-related data. As a result,
current studies perform multiple experiments in the same
subjects. While Bioconductor's methods and classes implemented
in different packages manage individual experiments, there is
not a standard class to properly manage different omic datasets
from the same subjects. In addition, most R/Bioconductor
packages that have been designed to integrate and visualize
biological data often use basic data structures with no clear
general methods, such as subsetting or selecting samples.
RESULTS: To cover this need, we have developed MultiDataSet, a
new R class based on Bioconductor standards, designed to
encapsulate multiple data sets. MultiDataSet deals with the
usual difficulties of managing multiple and non-complete data
sets while offering a simple and general way of subsetting
features and selecting samples. We illustrate the use of
MultiDataSet in three common situations: 1) performing
integration analysis with third party packages; 2) creating new
methods and functions for omic data integration; 3)
encapsulating new unimplemented data from any biological
experiment. CONCLUSIONS: MultiDataSet is a suitable class for
data integration under R and Bioconductor framework
MatemĂ tiques a partir de la fotografia. Proposta i anĂ lisi d'activitats
[cat] En el present treball s’ha pretès analitzar com la fotografia és un material
contextualitzat vĂ lid per desenvolupar activitats competencials de matemĂ tiques
a l’educació secundà ria obligatòria.
En la primera part s’ha estudiat la situació actual de les experiències didà ctiques
que fan ús de la fotografia dins l’à mbit matemà tic. Aquest ha estat el marc teòric
que ha permès establir uns criteris per configurar i avaluar la proposta didà ctica
que s’ha presentat.
En la segona part s’ha descrit la proposta didà ctica en forma d’activitats que
cobreixen continguts de cada un dels blocs del currĂculum de secundĂ ria. S’ha
realitzat un recull d’activitats, detallades amb guies pel professorat i per l’alumnat,
que puguin ser útils en un futur. De cada activitat s’ha realitzat una observació i
una valoraciĂł didĂ ctica.
El resultat d’aquest treball ha estat una proposta educativa que analitza un recurs
contextualitzat per treballar matemĂ tiques dins les aules de secundĂ ria
