Dear List Members,I am trying to set up a large system of equations and I am trying to find a simple way to set up  the list command under the package system fit. Here is the example from system fit and what I am trying to do:
EQ1 <- Y1 ~ X1 + X2 + X4EQ2 <- Y2 ~ X2 + X3EQ3 <- Y3 ~ X2 + X3 + X4EQ4 <- Y4 ~ X1 + X3 + X4eqSystem <-list(form1 = EQ1, form2 = EQ2, form3 = EQ3, form4 = EQ4)
#atempt 1 to "automate" above:eqSystem1 <-paste(paste("form", 1:4, sep=""), paste("EQ", 1:4,sep=""),sep="=")
#attempt 2  "automate" above:eqSystem2 <-as.list(paste(paste("form", 1:4, sep=""), paste("EQ", 1:4,sep=""),sep="="))

Here are the results:
The results that I want to get:> eqSystem1$form1Y1 ~ X1 + X2 + X4
$form2Y2 ~ X2 + X3
$form3Y3 ~ X2 + X3 + X4
$form4Y4 ~ X1 + X3 + X4
The results of my attempts:attempt 1: > eqSystem1 [1] "form1=EQ1" "form2=EQ2" "form3=EQ3" "form4=EQ4"
attempt 2:> eqSystem2[[1]]
[1] "form1=EQ1"

[[2]]
[1] "form2=EQ2"

[[3]]
[1] "form3=EQ3"

[[4]]
[1] "form4=EQ4"

Does anyone have any ideas on how to correct my code?
Thanks,
