summaryTotalDistance: Calculate total path distance

In wittja01/ballr: Analyze Data Generated from Syntech Servosphere Trials

Description

Calculate the total distance moved by an organism on the servosphere

Usage

summaryTotalDistance(list, summary.df = NA)

Arguments

list	A list of data frames, each of which has a column recording the distance moved during each recording period.
summary.df	The data frame object within which you are storing path summary variables. The default is NA if you do not currently have a summary data frame object started. When set to NA the function will create a new summary data frame. When an object is provided, the function will merge the summary data frame with the new data.

Details

Determine the total distance of a path taken by an organism on a servosphere.

Value

A named vector of numbers where each number corresponds to the total distance moved by an organism represented in the list of data frames. The numbers are ordered and named as they are in the data frames list.

Examples

# If a summary data frame has not been started

 servosphere <- list(data.frame(id = rep(1, 200),
                                stimulus = rep(c(0, 1), each = 100),
                                dT = sample(8:12, 200, replace = TRUE),
                                dx = runif(200, 0, 5),
                                dy = runif(200, 0, 5),
                                treatment = rep("a", 200),
                                date = rep("2032018", 200)),
                     data.frame(id = rep(2, 200),
                                stimulus = rep(c(0, 1), each = 100),
                                dT = sample(8:12, 200, replace = TRUE),
                                dx = runif(200, 0, 5),
                                dy = runif(200, 0, 5),
                                treatment = rep("b", 200),
                                date = rep("2032018", 200)))

servosphere <- calcDistance(servosphere)

summary_df <- summaryTotalDistance(servosphere, summary.df = NA)

# If a summary data frame has been started

summary_df <- data.frame(id = c(1, 2),
                         treatment = c("a", "b"),
                         date = c("2032018", "2042018"),
                         stimulus = c(0, 0))

summary_df <- summaryTotalDistance(servosphere, summary.df = summary_df)
