Re: [R] Newbie in R: Reading .txt files and storing the 'numbers' in a vector
I am also a newbie, but here are the few thing i do
eo=read.table(file="path where you have saved your text
file/xxx.txt",header=T, )
#this will only read excelfiles saved
as *.csv file
attach(eo)
#attach the data
names(eo)
go to this website http://www.statmethods.net/stats
here is how to store numbers as vectors
a<-c(1,2,3,4,5,6,7)
here is how i means as vector
d<-aggregate(LMMP8,list(PlateID,Self_T1D),mean, na.rm=T)
I would suggest u to search for website for R tutorials
here are some good ones
go to this website http://www.statmethods.net/stats
http://cran.r-project.org/doc/contrib/Lemon-kickstart/kr_ttest.html
this one has all the codes you can change them according to your data
http://www3.imperial.ac.uk/pls/portallive/docs/1/1171930.TXT
http://www.mayin.org/ajayshah/KB/R/index.html
also download the book by verjani it would be a great help to you.

Did you get the distinction between a vector and a dataframe?

I'm fairly certain you need a dataframe, hence the recommendation to
look at read.table.

Those will follow simply once you have the first part working.

[R] Newbie in R: Reading .txt files and storing the 'numbers' in a vector
Hello everybody,
I'm a newbie in R and just went through an introduction class recently.
Here's my problem.
I have 2 text files (.txt) with plain numbers ('doubles' for those who
know c++) ordered into 2 columns as below:
coordinate1 value1
coordinate2 value2
coordinate3 value3
... ...
coordinateN valueN
I would like to write a small programme in which i would:
1. take all values of file 1 and store them in a vector
2. substract to those all values of file 2 (one by one) and store the
result in a new vector
3. Create a sliding window of chosen size and calculate the
mathematical average and store these averages in a new vector
4. Plot the different graphes with a bar plot
So I wrote a c++ script that does the first parts and writes the
averages in a output.txt file (which I have up and running).
Unfortunately, I seem to fail in reading these as numbers and putting
them into a vector (in the R environment). I can read the file , but
this is what I get:
> z=scan(file = "/Users/NCCRGENETICS/Desktop/testRnumbers.txt", what
= "double")
Read 19 items
> z
[1] "{\\rtf1\\ansi\\ansicpg1252\\cocoartf949\\cocoasubrtf430"
[2] "{\\fonttbl\\f0\\fswiss\\fcharset0"
[3] "Helvetica;}"
[4] "{\\colortbl;\\red255\\green255\\blue255;}"
[5] "\\paperw11900\\paperh16840\\margl1440\\margr1440\\vieww9000\
\viewh8400\\viewkind0"
[6] "\\pard\\tx566\\tx1133\\tx1700\\tx2267\\tx2834\\tx3401\\tx3968\
\tx4535\\tx5102\\tx5669\\tx6236\\tx6803\\ql\\qnatural\\pardirnatural"
[7] "\\f0\\fs24"
[8] "\\cf0"
[9] "13\\" // This is where my file "should" start
reading the numbers I see in the window when I open it with textedit
[10] "27\\"
[11] "39\\"
[12] "48\\"
[13] "34\\"
[14] "17\\"
[15] "23\\"
[16] "45\\"
[17] "23\\"
[18] "4\\"
[19] "}"
>
Thanks so much to any of you who could provoid a little help... I'm
getting nuts.
