```Hello everyone,

I am having this data.frame. For each row you have 26 values aggregated in a cell and separated by a comma. I want to do some calculations for all unique names and taxonomy which include the four different damage states. I can estimate the results but i am struggling to save them in a data.frame and assign next to them the unique combination of the name, taxonomy. Any help much appreciated.

D2L <- c(0, 2, 10, 50, 100)

VC_final <- array(NA, length(distinct(d1[,c(65,4,3)])\$Name) )
VC       <- matrix(NA, length(distinct(d1[,c(65,4,3)])\$Name),length(unlist(str_split(as.character(d1[1,]\$Y_vals), pattern = ","))))

# get the rows for the four damage states
DS1_rows <- d1\$Damage_State ==  unique(d1\$Damage_State)[4]
DS2_rows <- d1\$Damage_State ==  unique(d1\$Damage_State)[3]
DS3_rows <- d1\$Damage_State ==  unique(d1\$Damage_State)[2]
DS4_rows <- d1\$Damage_State ==  unique(d1\$Damage_State)[1]

# step through all possible values of IM.type and Taxonomy and Name
#### This is true for this subset not generalibale needs to be checked first ##

for(IM in unique(d1\$IM_type)) {
for(Tax in unique(d1\$Taxonomy)) {
for(Name in unique(d1\$Name)) {
# get a logical vector of the rows to be use DS5 in this calculation
calc_rows <- d1\$IM_type == IM & d1\$Taxonomy == Tax & d1\$Name == Name

# check that there are any such rows in the DS5ata frame
if(sum(calc_rows)) {
cat(IM,Tax,Name,"\n")
# if so, fill in the four values for these rows
VC[calc_rows]  <- D2L[1] * (1- as.numeric(unlist(str_split(as.character(d1[calc_rows & DS1_rows,]\$Y_vals), pattern = ","))) ) +
D2L[2]* (as.numeric(unlist(str_split(as.character(d1[calc_rows & DS1_rows,]\$Y_vals), pattern = ","))) -
as.numeric(unlist(str_split(as.character(d1[calc_rows & DS2_rows,]\$Y_vals), pattern = ",")))) +
