Pearson cc.r (Gaucher Disease)

This is an R function we wrote to calculate the Pearson's correlation coefficients in the task 4. Below is the calculation with our values.

<source lang="perl"> r <- function(n,x,y){ xy <- x*y x2 <- x**2 y2 <- y**2 sumx <- sum(x) sumy <- sum(y) sumxy <- sum(xy) sumx2 <- sum(x2) sumy2 <- sum(y2) return ((n*sumxy-sumx*sumy)/sqrt((n*sumx2-sumx**2)*(n*sumy2-sumy**2))) }

r(n,ali_cols,lga_n) r(n,ali_cols,lga_id) r(n,ali_cols,rmsd) r(n,ali_cols,lga_s) r(n,ali_cols,lga_q)

r(n,hh_id,lga_n) r(n,hh_id,lga_id) r(n,hh_id,rmsd) r(n,hh_id,lga_s) r(n,hh_id,lga_q)

r(n,prob,lga_n) r(n,prob,lga_id) r(n,prob,rmsd) r(n,prob,lga_s) r(n,prob,lga_q)

r(n,evalue,lga_n) r(n,evalue,lga_id) r(n,evalue,rmsd) r(n,evalue,lga_s) r(n,evalue,lga_q)

r(n,score,lga_n) r(n,score,lga_id) r(n,score,rmsd) r(n,score,lga_s) r(n,score,lga_q) </source>

Alternative option is just to use the predefined R cor function: cor(x,y,method="pearson"). (We noticed that to late.)
