density {stats}

Kernel Density Estimation
Package: 
stats
Version: 
R 2.14.0

The (S3) generic function density computes kernel density
estimates. Its default method does so with the given kernel and
bandwidth for univariate observations.

file.path {base}

Construct Path to File
Package: 
base
Version: 
R 2.14.0

Construct the path to a file from components in a platform-independent
way.

which {base}

Which indices are TRUE?
Package: 
base
Version: 
R 2.14.0

Give the TRUE indices of a logical object, allowing for array
indices.

file.path {base}

Construct Path to File
Package: 
base
Version: 
R 2.14.0

Construct the path to a file from components in a platform-independent
way.

paretotol.int {tolerance}

Pareto (or Power Distribution) Tolerance Intervals
Package: 
tolerance
Version: 
0.3.0
Version: 
0.3.0
Package: 
tolerance

Provides 1-sided or 2-sided tolerance intervals for data distributed according to either a Pareto distribution or
a power distribution (i.e., the inverse Pareto distribution).

getSymbols {quantmod}

Load and Manage Data from Multiple Sources
Package: 
quantmod
Version: 
0.3-17
Version: 
0.3-17
Package: 
quantmod

Functions to load and manage Symbols in
specified environment. Used by specifyModel
to retrieve symbols specified in first step of modelling
procedure. Not a true S3 method, but methods for different
data sources follow an S3-like naming convention. Additional
methods can be added by simply adhering to the convention.

Current src methods available are: yahoo, google,
MySQL, FRED, csv, RData, and oanda.

Data is loaded silently without user
assignment by default.

ksvm {kernlab}

Support Vector Machines
Package: 
kernlab
Version: 
0.9-13
Version: 
0.9-13
Package: 
kernlab

Support Vector Machines are an excellent tool for classification,
novelty detection, and regression. ksvm supports the
well known C-svc, nu-svc, (classification) one-class-svc (novelty)
eps-svr, nu-svr (regression) formulations along with
native multi-class classification formulations and
the bound-constraint SVM formulations.
ksvm also supports class-probabilities output and
confidence intervals for regression.

lubridate {lubridate}

Dates and times made easy with lubridate...
Package: 
lubridate
Version: 
0.2.5
Version: 
0.2.5
Package: 
lubridate

Dates and times made easy with lubridate

Tweedie {tweedie}

Tweedie Distributions
Package: 
tweedie
Version: 
2.1.0
Version: 
2.1.0
Package: 
tweedie

Density, distribution function, quantile function and random
generation for the Tweedie family of distributions

periodReturn {quantmod}

Calculate Periodic Returns
Package: 
quantmod
Version: 
0.3-17
Version: 
0.3-17
Package: 
quantmod

Given a set of prices, return
periodic returns.
