Code Example 1
# In R there are many custom functions for reading files, but many of # them are essentially wrappers for read.table() and can be ignored. # Basic syntax using read.table(): data = read.table('/path/to/filename.extension', header=FALSE, sep="delimiter", skip=integer, nrows=integer, row.names=row_names, col.names=column_names) # Where: # - The above parameters are some of the most useful in read.table() # - Only the '/path/to/filename.extension' argument is required. It # can also be a complete URL to a file # - The header default is TRUE # - sep default is 'white space', which is one or more spaces, tabs, # newlines or carriage returns but it can be used to specify any # field delimiter e.g.: '\t' ',' '|' ';' and etc # - skip is the number of rows to skip when reading the file # - nrows is the maximum number of rows to read # - row.names and col.names are optional vectors of names that can be # used for the row or column names
