Error in from:to : NA/NaN argument
Hello R gurus,
I am having difficulties running a chunk of code that I otherwise thought
was correct..
> if (lower < max(length(IC_peaks),length(IC_valleys))) {
+ valley_index <- IC_valleys[lower+1]
+ for (i in seq(peak_index,valley_index-1)) {
+ IC_peaks_and_valleys <- c(IC_peaks_and_valleys, "v")
+ }
+ }
Error in from:to : NA/NaN argument

Converting a .txt file into a matrix
I need to convert foo.txt file into as.matrix
.txt file is a single column of numbers
(i.e.
-0.303904
-0.889965
-0.0270313
-0.387125
0.189837
-0.14858
-0.651178
-0.162632
0.449309
)
and I need to find out the correct syntax to read in this table as.matrix
I tried as.matrix(read.table(foo.txt)), but unfortunately this just spits
the table back out..
Any of your pointers would

plotting in R
Hello,
As a result of running linear discriminant analysis, I need to be able to
plot the resulting file. I am not sure what the best way to do this is. So
far I have tried regular plot("insert_file_name_here") command but the error
it gives me is Error in plot.new() : figure margins too large
here is sample LDA code I am working with ....

Linear Discriminant Analysis in R
Dear R gurus,
Thank you all for continuous support and guidance -- learning without you
would not be efficient.
I have a question regarding LD analysis and how to best code it up in R.
I have a file of (V52 and 671 time points across all columns) and another
file of phonetic features (each vowel is aligned with a distinct binary
sequence, i.e.
E 0 0 0 0 0 0 0 0 0 0 0 0 1 1 0 0 0 1 0 0 0 0 0 0

Help interpreting libarary(nnet) script output..URGENT
Hello,
I am pretty new to R. I am working on neural network classifiers and I am
feeding the nnet input from different regions of interest (fMRI data). The
script that I am using is this:
library (MASS)

data.frame(as.matrix(t(read.table(file="R_10_5runs_matrix9.txt")))*100000,syll
= c(rep("heap",3),rep("hoop",3),rep("hop",3)))
