# [R] cumulative sum by group and under some criteria

```Hi,

""

Thanks. I tried this code below, why does expanded dataset 'res1' has m1=3 and n1=3
, dataset 'd3' doesn't have m1=3, n1=3.

d3<-structure(list(m1 = c(2, 3, 2), n1 = c(2, 2, 3), cterm1_P0L = c(0.9025,
0.857375, 0.9025), cterm1_P1L = c(0.64, 0.512, 0.64), cterm1_P0H = c(0.9025,
0.9025, 0.857375), cterm1_P1H = c(0.64, 0.64, 0.512)), .Names = c("m1",
"n1", "cterm1_P0L", "cterm1_P1L", "cterm1_P0H", "cterm1_P1H"), row.names = c(NA,
3L), class = "data.frame")
d3
""
d3
#  m1 n1 cterm1_P0L cterm1_P1L cterm1_P0H cterm1_P1H
#1  2  2   0.902500      0.640   0.902500      0.640
#2  3  2   0.857375      0.512   0.902500      0.640
#3  2  3   0.902500      0.640   0.857375      0.512

Here, there is no row with m1=3 and n1=3.

d2<- data.frame()
#this was part of your original code.  In this, m1 is expanding on each value of n1
for (m1 in 2:3) {
for (n1 in 2:3) {
for (x1 in 0:(m1-1)) {
for (y1 in 0:(n1-1)) {
for (m in (m1+2): (7-n1)){
for (n in (n1+2):(9-m)){
for (x in x1:(x1+m-m1)){
for(y in y1:(y1+n-n1)){
d2<- rbind(d2,c(m1,n1,x1,y1,m,n,x,y))
}}}}}}}}
colnames(d2)<-c("m1","n1","x1","y1","m","n","x","y")   #Here the combination is there

expand.grid(2:3,2:3)
#  Var1 Var2
#1    2    2
#2    3    2
#3    2    3
#4    3    3

res1<-do.call(rbind,lapply(unique(d3\$m1),function(m1)
do.call(rbind,lapply(unique(d3\$n1),function(n1)
do.call(rbind,lapply(0:(m1-1),function(x1)
do.call(rbind,lapply(0:(n1-1),function(y1)
do.call(rbind,lapply((m1+2):(7-n1),function(m)
do.call(rbind,lapply((n1+2):(9-m),function(n)
do.call(rbind,lapply(x1:(x1+m-m1), function(x)
do.call(rbind,lapply(y1:(y1+n-n1), function(y)
expand.grid(m1,n1,x1,y1,m,n,x,y)) )))))))))))))))
names(res1)<- c("m1","n1","x1","y1","m","n","x","y")
attr(res1,"out.attrs")<-NULL res1[]<- sapply(d2,as.integer)
res1 #here too
identical(d2,res1)
#[1] TRUE

library(plyr)
res2<- join(res1,d3,by=c("m1","n1"),type="full")  #combination with m1=3, n1=3 didn't exist in d3, so that rows are left as missing or NA

tail(res2,3)
#   m1 n1 x1 y1 m n x y cterm1_P0L cterm1_P1L cterm1_P0H cterm1_P1H
#427  3  3  2  2 4 5 3 2         NA         NA         NA         NA
#428  3  3  2  2 4 5 3 3         NA         NA         NA         NA
#429  3  3  2  2 4 5 3 4         NA         NA         NA         NA

I hope it helps.

A.K.

Hi,
What I need is to expand each row by adding several columns and . Let me restate the question. I have a dataset d, I want to expand it to d2 showed below.
d<-data.frame()
for (m1 in 2:3) {
for (n1 in 2:2) {
for (x1 in 0:(m1-1)) {
for (y1 in 0:(n1-1)) {
d<-rbind(d,c(m1,n1,x1,y1))
}
}
}}
colnames(d)<-c("m1","n1","x1","y1")
d

m1 n1 x1 y1
1   2  2  0  0
2   2  2  0  1
3   2  2  1  0
4   2  2  1  1
5   3  2  0  0
6   3  2  0  1
7   3  2  1  0
8   3  2  1  1
9   3  2  2  0
10  3  2  2  1
I want to expand it as follows:
for (m in (m1+2): (7-n1){
for (n in (n1+2):(9-m){
for (x in x1:(x1+m-m1){
}}}
so for the first row,
m1 n1 x1 y1
1   2  2  0  0
it should be expanded as
m1 n1 x1 y1  m  n  x
2  2  0  0  4  4  0
2  2  0  0  4  4  1
2  2  0  0  4  4  2
2  2  0  0  4  5  0
2  2  0  0  4  5  1
2  2  0  0  4  5  2
