alternative way to do this:

load table of scoring

scoring=read.table("UWvMSU_1-22-13.txt",header=TRUE,sep="\t",stringsAsFactors=FALSE)

look at data

dim(scoring)
head(scoring)

preallocating matrix to store cumulative scores

cum_scores=matrix(NA,nrow(scoring)+1,3)
cum_scores[,1]=c(0,scoring[,1])
cum_scores[1,2:3]=0
colnames(cum_scores)=c("time","UW","MSU")

looping through individual scoring events

for(i in 1:nrow(scoring)){
if(scoring[i,2]=="UW"){
cum_scores[(i+1),2]=cum_scores[i,2]+scoring[i,3]
cum_scores[(i+1),3]=cum_scores[i,3]
}else{
cum_scores[(i+1),2]=cum_scores[i,2]
cum_scores[(i+1),3]=cum_scores[i,3]+scoring[i,3]
}
}
