readDataOT2: Read data files exported by OnTarget PC v2.* or OnTarget TDS v3.*

Description

Reads in data from files exported by OnTarget PC v2.* or OnTarget TDS v3.*. Several files can be read with one call.

Usage

readDataOT2(fPath = ".", fNames, fPat, combine = TRUE,
            dstTarget, conversion)

Value

With combine=FALSE: a list of data frames, each from one file that was read in. This list can then be combined into one big data frame by combineData.

file1

data frame containing data from the first file

file2

data frame containing data from the second file

...

more data frames

With combine=TRUE: a combined data frame from combineData.

Arguments

fPath

a character string containing the path to the folder with the OnTarget PC/TDS output files, e.g. 'c:/folder/otFiles'.

fNames

a character vector containing the file names of the files that should be read in.

fPat

a character string containing the regular-expression that describes all names of files that should be read in. E.g., '^points[[:digit:]]{2}\\.txt$' for filenames 'points**.txt', where ** are 2 digits. See regex, glob2rx.

combine

logical: combine the data into one big data frame with combineData?

dstTarget

a numerical value/vector giving the distance to the target - used in MOA calculation. Acts as override if variable distance is already included in the data.

conversion

how to convert the measurement unit for distance to target to that of the (x,y)-coordinates in MOA calculation. Example 'm2cm'. See getMOA.

Details

If fNames is provided, fPat is ignored.

If neither fNames nor fPat is provided, and we are in interactive mode under Windows, files can be chosen interactively.

This function is basically a wrapper for read.csv.

Output files need to be comma-separated files (file type .csv) from OnTarget PC v2.* or OnTarget TDS v3.*: 'Tools -> Export Point Data'. Files need to contain exactly the following variable names in this order: Project Title, Group, Ammunition, Distance, Aim X, Aim Y, Center X, Center Y, Point X, Point Y, and optionally Velocity.

Tested with OnTarget PC v2.10 and v2.28 as well as OnTarget TDS v3.71, v3.89, v6.09.
For reading in files exported from OnTarget PC v1.*, see readDataOT1.
For reading in other text files, see readDataMisc.

Examples

Run this code
if (FALSE) {
# folder with OnTarget PC v2.* or OnTarget TDS v3.* output files
fPath   <- 'c:/folder/otFiles'
fileNam <- c('pts01.csv', 'pts02.csv')   # desired files in that folder
DFgroup <- readDataOT2(fPath, fNames=fileNam, combine=TRUE)

## alternatively, specify filename pattern for all files to be read in
fPath   <- 'c:/folder/otFiles'            # folder with data files
fPat    <- '^pts[[:digit:]]{2}\\.txt$'  # filename pattern
DFgroup <- readDataOT2(fPath, fPat=pattern, combine=TRUE)
}

## result should look like this
data(DFcm)
head(DFcm)
