peek: peek at the top of a text file
In rafalib: Convenience Functions for Routine Data Exploration
peek R Documentation
peek at the top of a text file
Description
this returns a character vector which shows the top n lines of a file.
Note: I realized after the fact that this is essentially a duplicate
of the base R function readLines.
Usage
peek(x, n = 2)
Arguments
x
a filename
n
the number of lines to return

Examples
filename <- tempfile()
x<-matrix(round(rnorm(10^4),2),1000,10)
colnames(x)=letters[1:10]
write.csv(x,file=filename,row.names=FALSE)
peek(filename)
