ts is contained in the basic R installation, and the function HoltWinters() demands a ts time series. timeSeries has a completely different structure. It's also specifically directed towards finances. The big difference with ts is that it allows for irregular timeseries. The class ts can only hold equispaced series.

The function ts is used to create time-series objects. These are vectors or matrices with class of "ts" (and additional attributes) which represent data which has been sampled at equispaced points in time. In the matrix case, each column of the matrix data is assumed to contain a single (univariate) time series.

As mentioned above, "ts" is the basic class for regularly spaced time series using numeric time stamps. The zoo package provides infrastructure for regularly and irregularly spaced time series using arbitrary classes for the time stamps (i.e., allowing all classes from the previous section). It is designed to be as consistent as possible with "ts". R语言 中 时间序列 的内容主要有: 时间序列 的创建,A R MA模型的 建立 与自相关和偏自相关函数。.

Time Indexes (ti class) A time index has two parts: a tif (Time Index Frequency) code and a period. tif codes all lie in the open interval (1000..5000) and the period is a nonnegative number … The tsibble package provides a data class of tbl_ts to represent tidy temporal data. A tsibble consists of a time index, key, and other measured variables in a data-centric format, which is built on top of the tibble. Index An extensive range of indices are supported by tsibble: •native time classes in R (such as Date, POSIXct, and difftime) arima_diag(ts.obj, method = list(first = list(diff = 1, log = TRUE, title = "First Difference with Log Transformation")), cor = TRUE) Arguments ts.obj A ts object method A list, defines the transformation parameters of each plot.

Arguments dfxy. a data frame containing the two columns for the axes. fac. a factor partitioning the rows of the data frame in classes. wt. a vector of the point weightings of the data frame used for computing the means (star centers) and the ellipses of dispersion

The format is ts(vector, start=, end=, frequency=) where start and end are the times of the first and last observation and frequency is the number of observations per unit time (1=annual, 4=quartly, 12=monthly, etc.). # save a numeric vector containing 72 monthly observations 2017-09-19 · Notice that now when we plot the data, R recognizes that it is a ts object and plots the data as a line with dates along the x-axis. Aside from creating ts objects containing a single series of data, we can also create ts objects that contain multiple series. We can do this by passing a matrix rather than a vector to the x argument of ts().
