I have a question in R.
In directory H:/Delta_angle
I have 19 files like this:
ALA.delta
ASN.delta
ASP.delta
CYS.delta
GLN.delta
GLU.delta
HIS.delta
ILE.delta
LEU.delta
LYS.delta
MET.delta
PHE.delta
PRO.delta
SER.delta
THR.delta
TRP.delta
TYR.delta
VAL.delta
I want to read these files to 19 data
Hi
During using the R(vision 2.0.1), I meet a problem. I would like to do the
Multiple Correspondence Analysis, but when I use the "< mca(lf, nf = 2, abbrev
=
FALSE)", the sentence "Error: couldn't find function 'mca'" will appear. So,
please tell me how can I use the "mca()", thanks!
This question (paraphrase: How do I process a lot of homologous files?) or
something similar has been asked (and answered) a lot lately.
For example, look at this thread from today's posting to r-help:

By requesting 'help.search("mca")', I learned that mca was in
"library(MASS)". Did you try "library(MASS)" before your mca command?
hope this helps.

p.s. Using 'help.search' was suggested by the posting guide,
"www.R-project.org/posting-guide.html".

hi, guys:
I have a question on how to read data from file in which the length of each
line is unfixed.
For instance, the data in sample.dat are:
1 2 3 4
5 6 7
8
I want to read this kind of data into a matrix as:
1 2 3 4
5 6 7 0
8 0 0 0
Thank you
Jianbing Wu

Look at the `fill' argument in ?read.table.
This fills with NAs, but you can convert those to 0's later (although
it may be better to do this in the analysis).

Dear Sir,
I am using R to estimate two parameters in Normal distribution. I generated
100 normal distributed numbers, on which to estimate the parameter. The
syntax is:
fn<-function(x)-50*log((y)^2)+50*log(2*pi)-(1/2*(z^2))*(sum((x-y)^2))
out<-nlm(fn, x, hessian=TRUE)
but it does not work. Coul
Dear Sir
I am running a script file for fortran but it showing error i.e.
.sgb.x : /sbin/loader: Fatal Error : cannot map libm_c32.so
here sgb.x is its output file that I have got after running make file.
I have seached this library file inside /usr/shlib directory its not there.
Please tel me
