TCGAbiolinks retrieved molecular subtypes information from TCGA samples.
The functions `PanCancerAtlas_subtypes` and `TCGAquery_subtype` can be used to get the information tables.

While the `PanCancerAtlas_subtypes` function gives access to a curated table retrieved from synapse (probably with the most updated  molecular subtypes)
the `TCGAquery_subtype` function has the complete table also with sample information retrieved from the TCGA marker papers.

# `PanCancerAtlas_subtypes`: Curated molecular subtypes.

Data and description retrieved from synapse (https://www.synapse.org/#!Synapse:syn8402849)

Synapse has published a single file with all available molecular subtypes that have been described by TCGA (all tumor types and all molecular platforms), which can be accessed using the `PanCancerAtlas_subtypes` function as below:

```{r message=FALSE, warning=FALSE}
subtypes <- PanCancerAtlas_subtypes()
DT::datatable(subtypes,
             filter = 'top',
             options = list(scrollX = TRUE, keys = TRUE, pageLength = 5),
             rownames = FALSE)
```

The columns "Subtype_Selected" was selected as most prominent subtype classification (from the other columns)

# `TCGAquery_subtype`: Working with molecular subtypes data.

The Cancer Genome Atlas (TCGA) Research Network has reported integrated genome-wide 
studies of various diseases. We have added some of the subtypes defined by these
report in our package:

These subtypes will be automatically added in the summarizedExperiment
object through GDCprepare. But you can also use the `TCGAquery_subtype` function
to retrieve this information.

```{r, eval = FALSE}
lgg.gbm.subtype <- TCGAquery_subtype(tumor = "lgg")
```

A subset of the LGG subytpe is shown below:
```{r, eval = TRUE, echo = FALSE}
datatable(
  lgg.gbm.subtype[1:10,],
  caption = "Table with LGG molecular subtypes from TCGAquery_subtype",
  filter = 'top',
  options = list(scrollX = TRUE, keys = TRUE, pageLength = 5), 
  rownames = FALSE
)
```
