Relative Cumulative Frequency of Event Occurence
...art:
cumsum(E.occur)/(E.Occur)
The denominator E.Occur is a fixed value, instead of a moving count. I have
tried nrow(), length() but none provides a moving version of row count, as
cumsum does for the "True" values, occurring so far.

paired samples, matching rows, merge()
Hi everyone!
I'm matching two samples to create one sample that have
pairs of observations equal for the k1 variable. Merge()
doesn't work because I dont't want to recycle the values.
x <- data.frame(k1=c(1,1,2,3,3,5),
k2=c(20,21,22,23,24,25))
x
y <- data.frame(k1=c(1,1,2,2,3,4,5,5),
k2=c(10,11,12,13,14,15,16,17))
y
merge(x,y,by="k1")
k1 k2.x k2.y

Reading ASCII files
Dear all,
I need to read an ASCII file with diffent length lines.
This is what is contained in the file gene.txt:
1st line ID description snp_id genotype
2nd line 10003 Low rs152240
3rd line 10003 Moderate rs189011 TC
4th line 10004 Conservative rs152240 GC
5th line 10004 Bad rs154354
6th line 10013 Bad rs152240
7th line 10019 Conservative rs152240 AC
etc...
This is what I would like to obtain
