## compute PDX response

### Description

`response` Computes the drug response of an individual PDX model or batch.

### Usage

    response(object, model.id = NULL, batch = NULL,
      res.measure = c("mRECIST", "slope", "AUC", "angle", "abc", "TGI",
      "lmm"), treatment.only = FALSE, max.time = NULL,
      impute.value = TRUE, min.time = 10, concurrent.time = TRUE,
      vol.normal = FALSE, log.volume = FALSE, verbose = TRUE)

### Arguments

`object` | Xeva object.
`model.id` | `model.id` for which the durg response is to be computed.
`batch` | `batch.id` or experiment design for which the drug response is to be computed.
`res.measure` | Drug response measure. See `Details` below
`treatment.only` | Default `FALSE`. If `TRUE`, give data for non-zero dose periods only (if dose data are available).
`max.time` | Maximum time for data.
`impute.value` | Default `FALSE`. If `TRUE`, impute the missing values.
`min.time` | Default 10 days. Used for mRECIST computation.
`concurrent.time` | Default `FALSE`. If `TRUE`, cut the batch data such that control and treatment will end at same time point.
`vol.normal` | If TRUE it will normalize the volume. Default `FALSE`.
`log.volume` | If TRUE log of the volume will be used for response calculation. Default `FALSE`
`verbose` | Default `TRUE` will print information.

### Details

At present the following response measures are implemented

- mRECIST Computes mRECIST for individual PDX models

- slope Computes slope of the fitted individual PDX curves

- AUC Computes area under a PDX curve for individual PDX models

- angle Computes angle between treatment and control PDX curves

- abc Computes area between the treatment and control PDX curves

- TGI Computes tumor growth inhibition using treatment and control PDX curves

- lmm Computes linear mixed model (lmm) statistics for a PDX batch

### Value

Returns model or batch drug response object.

### Examples

    data(brca)
    response(brca, model.id="X.1004.BG98", res.measure="mRECIST")

    response(brca, batch="X-6047.paclitaxel", res.measure="angle")

    ed <- list(batch.name="myBatch", treatment=c("X.6047.LJ16","X.6047.LJ16.trab"),
                 control=c("X.6047.uned"))
    response(brca, batch=ed, res.measure="angle")
