Hi there
I am new user of r, i would need some help to translate som code for vectors
in matlab to r. I have managed to translate the first 7 rows, but not the
rest. Could anyone give me any suggestions for this problem??
Matlab code:
tempo=[];
temps=[];
tempn=[];
tempao=[];
tempas=[];
tempan=[];
for k=1:5
tempo = [tempo n_o(k,:)];
temps = [temps n_s(k,:)];
tempn = [tempn n_n(k,:)];
tempao = [tempao nanst_o(k,:)];
tempas = [tempas nanst_s(k,:)];
tempan = [tempan nanst_n(k,:)];
end.
This is the code that i?m trying to translate into r, so far i have managed
to translate the first 7 rows into r, but not last 6 rows.
R-Code:
tempao= vector()
tempas= vector()
tempan= vector()
tempao= vector()
tempas= vector()
tempan= vector()
for (k in 5:1)
?

Translation of matlab vectors code into r
3 messages · Haio, R. Michael Weylandt, Hans W Borchers
Perhaps read An Intro to R (shipped with every packaging of R -- type help.start() to get it) and then look at http://cran.r-project.org/doc/contrib/Hiebeler-matlabR.pdf n_o, nan_s, etc. are not functions I have in my Matlab distribution so I can't give more advice without knowing what they actually do. Your loop is wrong though: 1:5 in Matlab translates to 1:5 in R, not 5:1 Michael

This is extremely bad Matlab code, I would discourage you to translate it
line by line. What the code does:
It takes each of the matrices n_o, n_s, n_n, nanst_o, nanst_s, nanst_n
and combines the first five lines into vectors each. A way to do this in R
could be as follows:
tempo <- c(t(n_o[1:5, ]))
# etc.
where n_o, etc. will be the same matrices as in your Matlab example.
A similar solution, of course, would be possible in Matlab.
