As ("trip", other-classes)

Description

Coercing trip objects to other classes.

Function to create a SpatialLinesDataFrame from a trip object, resulting in a line segment for each implicit segment along the tracks. The object stores the start and end times, duration and the ID of the segment.

Usage

## S3 method for class 'trip'
as.ppp(X, ..., fatal)

## S3 method for class 'trip'
as.psp(x, ..., from, to)

as.track_xyt.trip(x, ..., from, to)

explode(x, ...)

Arguments

X

trip object.

...

reserved for future methods

fatal

Logical value, see Details of as.ppp

x

trip object

from

see as.psp for that method.

to

See as.psp.

Value

ppp object

psp object

SpatialLinesDataFrame

SpatialLinesDataFrame object with each individual line segment identified by start/end time and trip ID

Examples

d <- data.frame(x=1:10, y=rnorm(10), tms=Sys.time() + 1:10, id=gl(2, 5))
sp::coordinates(d) <- ~x+y
tr <- trip(d, c("tms", "id"))

as(tr, "ppp")
d <- data.frame(x=1:10, y=rnorm(10), tms=Sys.time() + 1:10, id=gl(2, 5))
tr <- trip(d, c("tms", "id"))

 as(tr, "psp")
 as.psp(tr)
 d <- data.frame(x=1:10, y=rnorm(10), tms=Sys.time() + 1:10, id=gl(2, 5))
 tr <- trip(d)

spldf <- explode(tr)
summary(tr)
