In-sample or out-of-sample accuracy measures for forecast grouped and hierarchical model
description
Returns a range of summary measures of the forecast accuracy. The function measures out-of-sample forecast accuracy based on (holdout data - forecasts) and in-sample accuracy at the bottom level when setting keep.fitted = TRUE in the forecast.gts. All measures are defined and discussed in Hyndman and Koehler (2006).
Function throw [R.oo v1.22.0]

title
Throws an Exception
description
Throws an exception similar to stop(), but with support for Exception classes. The first argument (object) is by default pasted together with other arguments (...) and with seperator sep="". For instance, to throw an exception, write throw("Value out of range: ", value, "."). which is short for throw(Exception("Value out of range: ", value, ".")). Note that throw() can be defined for classes inheriting Exception, which can then be caught (or not) using tryCatch().

title
Error bar plotting
description
A function to dd x and y error bars to plots. Low and high error bars can be generated.
Function check.named.vector [spatstat.utils v1.13-0]
keywords
error
title
Check Whether Object Has Required Components
description
These functions check whether the object x has components with the required names, and does not have any unexpected components.

Error Loop to Correct Final Correlation of Simulated Variables
description
This function attempts to correct the final pairwise correlations of simulated variables to be within epsilon of the target correlations. It updates the intermediate normal correlation iteratively in a loop until either the maximum error is less than epsilon or the number of iterations exceeds maxit. This function would not ordinarily be called directly by the user. The function is a modification of Barbiero & Ferrari's ordcont function in GenOrd-package. The ordcont function has been modified in the following ways: 1) It works for continuous, ordinal (r >= 2 categories), and count (regular or zero-inflated, Poisson or Negative Binomial) variables. 2) The initial correlation check has been removed because the intermediate correlation matrix Sigma from corrvar or corrvar2 has already been checked for positive-definiteness and used to generate variables. 3) Eigenvalue decomposition is done on Sigma to impose the correct intermediate correlations on the normal variables. If Sigma is not positive-definite, the negative eigenvalues are replaced with 0. 4) The final positive-definite check has been removed. 5) The intermediate correlation update function was changed to accommodate more situations. 6) Allowing specifications for the sample size and the seed for reproducibility. The vignette Variable Types describes the algorithm used in the error loop.

Checking Wave objects
description
Internal S4 generic function that checks for some kind of equality of objects of class Wave or class WaveMC.
Function expectStop [splus2R v1.2-2]
keywords
error
title
Test whether expected stop() or warning() messages are produced.
description
These functions are for use in automated testing using do.test, to test whether function give specified stop and warning messages.
Function timeout [fscaret v0.9.4.4]
keywords
error
title
timeout
description
This function limits elapsed time spent on single model development. It uses low-level functions of parallel packege and sets the fork process with time limit. If the result is not returned within set time, it kills fork. Function shouldn't be called from R console. The function is not used under Windows OS. Only Unix-like systems have fork functionality.

Easy and Flexible Input for One- and Two Dimensional Data
description
The function accepts one- or two dimensional data, checks them for compatibility and gives a dataframe back.

keywords
error
title
Aborts the current expression call
description
Aborts the current expression call and returns to the top level prompt/browser without signalling a condition.
