read.data: Read in Common Data File Extensions

Description

A single function to read in common data file extensions. Note that this function is specialized for reading in text data in the format necessary for functions in SemNetCleaner

File extensions supported:

• .Rdata

• .rds

• .csv

• .xlsx

• .xls

• .sav

• .txt

• .mat

• .dat

Usage

read.data(file = file.choose(), header = TRUE, sep = ",", ...)

Arguments

file

Character. A path to the file to load. Defaults to interactive file selection using file.choose

header

Boolean. A logical value indicating whether the file contains the names of the variables as its first line. If missing, the value is determined from the file format: header is set to TRUE if and only if the first row contains one fewer field than the number of columns

sep

Character. The field separator character. Values on each line of the file are separated by this character. If sep = "" (the default for read.table) the separator is a 'white space', that is one or more spaces, tabs, newlines or carriage returns

...

Additional arguments. Allows for additional arguments to be passed onto the respective read functions. See documentation in the list below:

• .Rdata load

• .rds readRDS

• .csv read.table

• .xlsx read_excel

• .xls read_excel

• .sav read.spss

• .txt read.table

• .mat readMat

• .dat read.table

Value

A data frame containing a representation of the data in the file. If file extension is ".Rdata", then data will be read to the global environment
