readGCTX {slinky} | R Documentation

## readGCTX

### Description

Read portions of data matrix from LINCS gctx datafile

### Usage

    readGCTX(x)

    ## S4 method for signature 'Slinky'
    readGCTX(x)

### Arguments

`x` | a Slinky Object

### Value

Matrix of expression data with rownames and colnames appropriately set. If a subset of the data is desired, subset the slinky object itself, not the resulting data matrix. That is, `data <- readGCTX(x[1:50,1:500])` will be MUCH faster than `ndata <- readGCTX(x)[1:50, 1:500]`.

### Examples

    # for build/demo only.  You MUST use your own key when using the slinky
    # package.
    user_key <- httr::content(httr::GET('https://api.clue.io/temp_api_key'),
                              as='parsed')$user_key
    sl <- Slinky(user_key,
                     system.file('extdata', 'demo.gctx',
                          package='slinky'),
                     system.file('extdata', 'demo_inst_info.txt',
                         package = 'slinky'))
    data <- readGCTX(sl[1:20,1:5])
