rounding {INQC}

Detects rounded sections

Description

This function splits data by month and looks if a decimal value is repeated too many times

Usage

rounding(y, blocksize = 20)

Arguments

y

two columns with date in the ECA&D format (yyyymmdd) and data

blocksize

maximum number of repeated values with the same decimal allowed on each block (blocks = months)

Value

list of positions which do not pass this QC test. If all positions pass the test, returns NULL

Examples

#Extract the ECA&D data file from the example data folder
path2inptfl<-system.file("extdata", "TX_SOUID132734.txt", package = "INQC")
#Read the data file
y<-readecad(input=path2inptfl,missing= -9999)[,3:4]
#Introduce the rounding errors in first 50 data values
y[1:50,2]<-round((y[1:50,2])/10)*10
#Find all suspicious positions in the time series
rounding(y,blocksize=20)
