In onlineforecast: Forecast Modelling for Online Applications

Summary with checks of the data.list for appropriate form.

Description

Summary including checks of the data.list for appropriate form.

Usage

## S3 method for class 'data.list'
summary(
  object,
  printit = TRUE,
  stopit = TRUE,
  nms = names(object),
  msgextra = "",
  ...
)

Arguments

object	The object to be summarized and checked
printit	A boolean deciding if check results tables are printed
stopit	A boolean deciding if the function stop with an error if the check is not ok
nms	A character vector. If given specifies the variables (vectors or matrices) in object to check
msgextra	A character which is added in the printout of an (potential) error message
...	Not used

Details

Prints on table form the result of the checks.

Value

The tables generated.

Checking the data.list for appropriate form:

A check of the time vector t, which must have equidistant time points and no NAs.

Then the results of checks of vectors (observations):

- NAs: Proportion of NAs

- length: Same length as the 't' vector?

- class: The class of the vector

Then the results of checking data.frames and matrices (forecasts):

- maxHorizonNAs: The proportion of NAs for the horizon (i.e. column) with the highest proportion of NAs

- meanNAs: The proportion of NAs of the entire matrix

- nrow: Same length as the 't' vector?

- colnames: Columns must be names 'kx', where 'x' is the horizon (e.g. k12 is 12-step horizon)

- sameclass: Error if not all columns are the same class

- class: Prints the class of the columns if they are all the same

Examples

summary(Dbuilding)

# Some NAs in k1 forecast
D <- Dbuilding
D$Ta$k1[1:1500] <- NA
summary(D)

# Vector with observations not same length as t throws error
D <- Dbuilding
D$heatload <- D$heatload[1:10]
try(summary(D))

# Forecasts wrong count
D <- Dbuilding
D$Ta <- D$Ta[1:10, ]
try(summary(D))

# Wrong column names
D <- Dbuilding
names(D$Ta)[4] <- "xk"
names(D$Ta)[2] <- "x2"
try(summary(D))

# No column names
D <- Dbuilding
names(D$Ta) <- NULL
try(summary(D))

# Don't stop or only print if stopped 
onlineforecast:::summary.data.list(D, stopit=FALSE)
try(onlineforecast:::summary.data.list(D, printit=FALSE))

# Only check for specified variables
# (e.g. do like this in model functions to check only variables used in model)
onlineforecast:::summary.data.list(D, nms=c("heatload","I"))
