### Retrieve SeSAMe data

Source: https://github.com/zwdzwd/sesamedata/blob/devel/man/sesameDataGet.Rd

Caches the specified data object and then retrieves it into the workspace.

```R
sesameDataCache("EPIC.1.SigDF")
EPIC.1.SigDF <- sesameDataGet('EPIC.1.SigDF')
```

### sesameDataList(filter = NULL, full = FALSE)

Source: https://github.com/zwdzwd/sesamedata/blob/devel/man/sesameDataList.Rd

Lists all available SeSAMe data titles, with optional filtering and column display settings.

```APIDOC
## sesameDataList

### Description
Lists all available SeSAMe data titles. Users can optionally filter the results by a keyword or choose to display all columns.

### Usage
`sesameDataList(filter = NULL, full = FALSE)`

### Parameters
- **filter** (character) - Optional - A keyword used to filter the data titles.
- **full** (logical) - Optional - If set to TRUE, displays all columns in the output.

### Returns
- Returns a list or vector of titles from SeSAMe Data.

### Example
```R
sesameDataList("KYCG")
```
```

--------------------------------

### sesameDataHas(data_titles)

Source: https://github.com/zwdzwd/sesamedata/blob/devel/man/sesameDataHas.Rd

Checks if the provided data titles exist in the sesameData repository.

```APIDOC
## sesameDataHas

### Description
Checks whether specific data titles are available in the sesameData repository.

### Signature
`sesameDataHas(data_titles)`

### Parameters
- **data_titles** (character vector) - Required - A vector of data titles to check for existence.

### Returns
- **boolean vector** - A logical vector of the same length as `data_titles`, where TRUE indicates the data exists and FALSE indicates it does not.

### Example
```r
sesameDataHas(c("EPIC.address", "EPIC.address.Nonexist"))
```
```

--------------------------------

### Query Probes by Region or Gene

Source: https://github.com/zwdzwd/sesamedata/blob/devel/vignettes/sesameData.Rmd

Retrieve probe information based on specific genomic regions or gene associations.

```r
## probes in a region
sesameData_getProbesByRegion(GRanges('chr5',
    IRanges(135313937, 135419936)), platform = 'Mammal40')
## get chrX probes
sesameData_getProbesByRegion(chrm = 'chrX', platform = "Mammal40")
## get autosomal probes
sesameData_getProbesByRegion(
    chrm_to_exclude = c("chrX", "chrY"), platform = "Mammal40")
## get DNMT3A probes
sesameData_getProbesByGene('DNMT3A', "Mammal40", upstream=500)
## get DNMT3A promoter probes
sesameData_getProbesByGene('DNMT3A', "Mammal40", promoter = TRUE)
## get all promoter probes
sesameData_getProbesByGene(NULL, "Mammal40", promoter = TRUE)
```

--------------------------------

### Cache specific SeSAMe data

Source: https://github.com/zwdzwd/sesamedata/blob/devel/man/sesameDataCache.Rd

Caches the specified data title to the local environment.

```R
sesameDataCache("genomeInfo.hg38")
```

--------------------------------

### sesameData_txnToGeneGRanges(txns)

Source: https://github.com/zwdzwd/sesamedata/blob/devel/man/sesameData_txnToGeneGRanges.Rd

Converts a GRanges object containing transcript information into a GRanges object containing gene information.

```APIDOC
## sesameData_txnToGeneGRanges

### Description
Converts transcript GRanges to gene GRanges.

### Parameters
- **txns** (GRanges) - Required - A GRanges object representing transcripts.

### Returns
- **GRanges** - A GRanges object representing genes.

### Example
```R
txns <- sesameData_getTxnGRanges("mm10")
genes <- sesameData_txnToGeneGRanges(txns)
```
```

--------------------------------

### Retrieve Transcript GRanges

Source: https://github.com/zwdzwd/sesamedata/blob/devel/vignettes/sesameData.Rmd

Retrieve transcript-centric GRanges objects or collapse isoforms to gene level.

```r
sesameData_getTxnGRanges("mm10")
```

```r
sesameData_getTxnGRanges("mm10", merge2gene=TRUE)
```
