I entered this data set using the command 'read.csv'. I want to
exclude values fewer than zero in column 2 so then I tried the
following command:

Novice question about getting data into R

read data from a file, and I get the following errors:

> = TRUE)
Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings,

read.csv reads more rows than indicated by wc -l
When I have a csv file that is more than 6 lines long, not including
the header, and one of the fields is blank for the last few lines, and
there is an extra comma on of the lines with the blank field,
read.csv() makes creates an extra line.
I attached an example file; I'll also paste the contents here:
A,apple
A,orange
A,orange
A,orange

Creating the right table from lapply list
Perhaps this toy example will help:
## example data
output <- list(1:5, 1:7, 1:4)
lens <- lapply(output, length)
maxlen <- max(unlist(lens))
outputmod <- lapply(output, function(x, maxl) c(x, rep(NA, maxl-length(x))), maxl=maxlen)
outputmat <- do.call(cbind, outputmod)
write.csv(outputmat, na='')
The idea is to pad the shorter vectors with NA (missing) before converting

Hey,
I just googled my error and many things came up. I followed the leads and

TRUE-- but I've still been having trouble fixing it, so I would greatly
appreciate any help you can provide. Here is my code:

Getting started with R
I've got a background in computer science & have been using Linux for
nearly a decade. I'm working on a Ph.D. in education and technology
and I essentially live in emacs and do all of my writing in LaTeX.
To me R seems like the perfect stats package. Unfortunately, the
learning curve is killing me. I feel like that if I'd waded through
pulling down menus in SPSS or SAS I could

Matrix to data frame conversion
I have a matrix which I wanted to convert to a data frame. As I could not
succeed and resorted to export to csv and reimport it again. Why did I fail
in the attempt and how can I achieve what I wanted without this
roundabouts?
The original matrix:

num [1:90, 1:4] 3.5938 0.0274 0.0342 0.0135 0.0207 ...

using the command:
dataframe<-read.table("/path/to/file.csv",header=T,row.names=1)
When I try the command:
dataframe[,2]
I receive the response:

I was expecting:
row1 0.2
row2 0.4
What is my error with the syntax please?

Import selected columns from sas7bdat file
hi, the sas universal viewer might be a free, non-R way to convert a
sas7bdat file to non-proprietary formats, not sure if it's windows-only.
those other formats should be easier to import only a subset of columns
into R..

Append to csv without header
Hi,
I am writing a function that writes to a csv file for every call.
However, for the subsequent calls, I want to append the data to the existing

I tried searching in the previous posts, but I am stuck with different
