Hi all,

I want to create a new matrix based on a previous matrix.

You see, If my "data" matrix accomplises this:

if(rowSums(data[i,])>16|rowSums(data[i,])<28)
 data[i,]= data[i,]

# if sum of rows is more than 16 and less 28 I conservate the row
#but How I say if else "remove" the line (I tried this) but doesn´t
works...I´m really a asn

else if(data[i,]=data[-i,])
}

You see imagine my data matrix is 10x4 and only 3 rows passes the
condition...the resulting matrix will be 3x4

I tried also to save the new matrix as csv like this

write.csv(data, file = "input1.csv")

How should I proceed to save as a txt?

Many thanks I really like this problems but I feel my mind is restricted to
more easy things¡¡¡jajaj
