Coerce, Extractor, and Replacement methods for class "TDR" objects

Share:

Description

Basic methods for manipulating objects of class TDR.

Show Method

show

signature(object="TDR"): print an informative summary of the data.

Coerce Methods

as.data.frame

signature(x="TDR"): Coerce object to data.frame. This method returns a data frame, with attributes “file” and “dtime” indicating the source file and the interval between samples.

as.data.frame

signature(x="TDRspeed"): Coerce object to data.frame. Returns an object as for TDR objects.

as.TDRspeed

signature(x="TDR"): Coerce object to TDRspeed class.

Extractor Methods

[

signature(x="TDR", i="numeric", j="missing", drop="missing"): Subset a TDR object; these objects can be subsetted on a single index i. Selects given rows from object.

getDepth

signature(x = "TDR"): depth slot accessor.

getCCData

signature(x="TDR", y="missing"): concurrentData slot accessor.

getCCData

signature(x="TDR", y="character"): access component named y in x.

getDtime

signature(x = "TDR"): sampling interval accessor.

getFileName

signature(x="TDR"): source file name accessor.

getTime

signature(x = "TDR"): time slot accessor.

getSpeed

signature(x = "TDRspeed"): speed accessor for TDRspeed objects.

Replacement Methods

depth<-

signature(x="TDR"): depth replacement.

speed<-

signature(x="TDR"): speed replacement.

ccData<-

signature(x="TDR"): concurrent data frame replacement.

data(divesTDR)

## Retrieve the name of the source file
getFileName(divesTDR)
## Retrieve concurrent temperature measurements
temp <- getCCData(divesTDR, "temperature"); head(temp)
temp <- getCCData(divesTDR); head(temp)

## Coerce to a data frame
dives.df <- as.data.frame(divesTDR)
head(dives.df)

## Replace speed measurements
newspeed <- getSpeed(divesTDR) + 2
speed(divesTDR) <- newspeed
