In santaR: Short Asynchronous Time-Series Analysis

Generate a Ind x Time + Var data.frame concatenating all variables from input variable

Description

Generate Ind x Time data.frame for each variable using get_ind_time_matrix and then concatenate all variables rowise. Resulting data.frame contrain Time as columns and Individuals and Variables as rows. Pairs of Individual and Timepoint without a measurement are left as NA. If ncore!=0 the function is parallelised, however the parallelisation overhead cost is high if not required.

Usage

get_eigen_spline_matrix(inputData, ind, time, ncores = 0)

Arguments

inputData	data.frame of measurements with observations as rows and variables as columns
ind	Vector of subject identifier (individual) corresponding to each measurement
time	Vector of time corresponding to each measurement
ncores	(int) Number of cores to use for parallelisation. Default 0 for no parallelisation.

Value

data.frame of measurements for each IND x TIME + VAR. Rows are unique Individual IDs per variable, and columns unique measurement Time. Pairs of (IND,TIME+VAR) without a measurement are left as NA.

Examples

## Not run: 
## 6 measurements, 3 subjects, 3 unique time-points, 2 variables
inputData <- matrix(c(1,2,3,4,5,6, 7,8,9,10,11,12), ncol=2)
ind  <- c('ind_1','ind_1','ind_1','ind_2','ind_2','ind_3')
time <- c(0,5,10,0,10,5)
get_eigen_spline_matrix(inputData, ind, time, ncores=0)
#     0   5  10
# 1   1   2   3
# 2   4  NA   5
# 3  NA   6  NA
# 4   7   8   9
# 5  10  NA  11
# 6  NA  12  NA

## End(Not run)
