# Class `"cpt.geo"` A class for cpt.geo objects. 1.1 class ## Objects from the Class Objects can be created by calls of the form `new("cpt.geo", ...)`. - **`new('cpt.geo',...)`:**: Creates a new object with class cpt.geo ## Slots - **`data.set`:**: Object of class `"matrix"`, original data set to be analyzed for changepoints - **`distance`:**: Object of class `"numeric"`, distance mapping of each time vector. - **`angle`:**: Object of class `"numeric"`, angle mapping of each time vector. - **`penalty`:**: Object of class `"character"`, type of penalty used as a text string. - **`pen.value`:**: Object of class `"numeric"`, numeric value of penalty used. - **`test.stat`:**: Object of class `"character"`, test statistic used for the analysis. - **`msl`:**: Object of class `"numeric"`, minimum segment length (no. of observations between changepoints). - **`nquantiles`:**: Object of class `"numeric"`, number of quantiles used in the empirical distribution. - **`dist.cpts`:**: Object of class `"numeric"`, changepoint locations in the distances. - **`ang.cpts`:**: Object of class `"numeric"`, changepoint locations in the angles. - **`date`:**: Object of class `"character"`, date the analysis was run. - **`version`:**: Object of class `"character"`, version number of the package when analysis was run. ## Methods - **ang.cpts**: `signature(object = "cpt.geo")`: retrieves ang.cpts slot. - **ang.cpts<-**: `signature(object = "cpt.geo")`: replaces ang.cpts slot. - **angle**: `signature(object = "cpt.geo")`: retrieves angle slot. - **angle<-**: `signature(object = "cpt.geo")`: replaces angle slot. - **data.set**: `signature(object = "cpt.geo")`: retrieves data.set slot. - **data.set<-**: `signature(object = "cpt.geo")`: replaces data.set slot. - **dist.cpts**: `signature(object = "cpt.geo")`: retrieves dist.cpts slot. - **dist.cpts<-**: `signature(object = "cpt.geo")`: replaces dist.cpts slot. - **distance**: `signature(object = "cpt.geo")`: retrieves distance slot. - **distance<-**: `signature(object = "cpt.geo")`: replaces distance slot. - **msl**: `signature(object = "cpt.geo")`: retrieves msl slot. - **msl<-**: `signature(object = "cpt.geo")`: replaces msl slot. - **nquantiles**: `signature(object = "cpt.geo")`: retrieves nquantiles slot. - **nquantiles<-**: `signature(object = "cpt.geo")`: replaces nquantiles slot. - **pen.value**: `signature(object = "cpt.geo")`: retrieves pen.value slot. - **pen.value<-**: `signature(object = "cpt.geo")`: replaces pen.value slot. - **penalty**: `signature(object = "cpt.geo")`: retrieves penalty slot. - **penalty<-**: `signature(object = "cpt.geo")`: replaces penalty slot. - **plot**: `signature(object = "cpt.geo")`: returns an object from ggplot of the distance and angle mappings. - **show**: `signature(object = "cpt.geo")`: prints details of the cpt.geo object including a summary. - **summary**: `signature(object = "cpt.geo")`: prints a summary of the cpt.geo object. - **test.stat**: `signature(object = "cpt.geo")`: retrieves test.stat slot. - **test.stat<-**: `signature(object = "cpt.geo")`: replaces test.stat slot. ## Author(s) Thomas Grundy ## See Also `geomcp`,`plot-methods`,`ggplot` ## Examples ```r showClass("cpt.geo") #shows the structure of the cpt.geo class. x=new('cpt.geo') #creates a new object with the cpt.geo class defaults dist.cpts(x) #retrieves the dist.cpts slot from x dist.cpts(x) <- c(50,100) #replaces the dist.cpts slot from x with c(50,100) ```
