struggling with pairlists

It was not clear what you were asking for.  Did you want a 'list' of
'lists' pairs?  What are you going to use the data for?  How are you
expecting to access it?  This will create a list similar to:

z <- list(list(variable="TrendOff", value=0), list(.......

flags_val <- c( 0,1,1,1,4,1,1,1,4,1,1,1,4,1,1,1,4,1,1)
 flags_nam <- c("TrendOff","MOdwt","ZeroPadding",

+                 "Step1HSOff","Step1NumHSOff","Step1NumHSOff","Step1ExtOff",
+                 "Step2HSOff","Step2NumHSOff","Step2NumHSOff","Step2ExtOff",
+                "Step3HSOff","Step3NumHSOff","Step3NumHSOff","Step3ExtOff",
+                "Step4HSOff","Step4NumHSOff","Step4NumHSOff","Step4ExtOff" )

x <- lapply(seq_along(flags_val), function(z){

+     list(variable=flags_nam[z], value=flags_val[z])
+ })

dput(x)

list(structure(list(variable = "TrendOff", value = 0), .Names = c("variable",
"value")), structure(list(variable = "MOdwt", value = 1), .Names =
c("variable",
"value")), structure(list(variable = "ZeroPadding", value = 1), .Names
= c("variable",
"value")), structure(list(variable = "Step1HSOff", value = 1), .Names
= c("variable",
"value")), structure(list(variable = "Step1NumHSOff", value = 4),
.Names = c("variable",
"value")), structure(list(variable = "Step1NumHSOff", value = 1),
.Names = c("variable",
"value")), structure(list(variable = "Step1ExtOff", value = 1), .Names
= c("variable",
"value")), structure(list(variable = "Step2HSOff", value = 1), .Names
= c("variable",
"value")), structure(list(variable = "Step2NumHSOff", value = 4),
.Names = c("variable",
"value")), structure(list(variable = "Step2NumHSOff", value = 1),
.Names = c("variable",
"value")), structure(list(variable = "Step2ExtOff", value = 1), .Names
= c("variable",
"value")), structure(list(variable = "Step3HSOff", value = 1), .Names
= c("variable",
"value")), structure(list(variable = "Step3NumHSOff", value = 4),
.Names = c("variable",
"value")), structure(list(variable = "Step3NumHSOff", value = 1),
.Names = c("variable",
"value")), structure(list(variable = "Step3ExtOff", value = 1), .Names
= c("variable",
"value")), structure(list(variable = "Step4HSOff", value = 1), .Names
= c("variable",
"value")), structure(list(variable = "Step4NumHSOff", value = 4),
.Names = c("variable",
"value")), structure(list(variable = "Step4NumHSOff", value = 1),
.Names = c("variable",
"value")), structure(list(variable = "Step4ExtOff", value = 1), .Names
= c("variable",
"value")))

I would like to create a vector of pairlist (flag, binary_value) ?like:

?(variable ="TrendOff", ? ? value = 0)
?(variable ="MOdwt", ? ? ? ?value = 1)
?(variable ? "ZeroPadding", value =1)
?................................................

I tried the following syntax but the emcompassing list (that I called "flags") is not made up of pairlists. Instead it is
made up of two apparently disjoint lists:

flags_val <- c( 0,1,1,1,4,1,1,1,4,1,1,1,4,1,1,1,4,1,1)
?flags_nam <- c("TrendOff","MOdwt","ZeroPadding",

+ ? ? ? ? ? ? ? ? "Step1HSOff","Step1NumHSOff","Step1NumHSOff","Step1ExtOff",
+ ? ? ? ? ? ? ? ? "Step2HSOff","Step2NumHSOff","Step2NumHSOff","Step2ExtOff",
+ ? ? ? ? ? ? ? ? "Step3HSOff","Step3NumHSOff","Step3NumHSOff","Step3ExtOff",
+ ? ? ? ? ? ? ? ? "Step4HSOff","Step4NumHSOff","Step4NumHSOff","Step4ExtOff" )

?flags_nam

?[1] "TrendOff" ? ? ?"MOdwt" ? ? ? ? "ZeroPadding" ? "Step1HSOff" ? ?"Step1NumHSOff" "Step1NumHSOff"
?[7] "Step1ExtOff" ? "Step2HSOff" ? ?"Step2NumHSOff" "Step2NumHSOff" "Step2ExtOff" ? "Step3HSOff"
[13] "Step3NumHSOff" "Step3NumHSOff" "Step3ExtOff" ? "Step4HSOff" ? ?"Step4NumHSOff" "Step4NumHSOff"
[19] "Step4ExtOff"

flags <- pairlist (data = flags_val, variable = flags_nam)
flags

$data
?[1] 0 1 1 1 4 1 1 1 4 1 1 1 4 1 1 1 4 1 1

$variable
?[1] "TrendOff" ? ? ?"MOdwt" ? ? ? ? "ZeroPadding" ? "Step1HSOff" ? ?"Step1NumHSOff" "Step1NumHSOff"
?[7] "Step1ExtOff" ? "Step2HSOff" ? ?"Step2NumHSOff" "Step2NumHSOff" "Step2ExtOff" ? "Step3HSOff"
[13] "Step3NumHSOff" "Step3NumHSOff" "Step3ExtOff" ? "Step4HSOff" ? ?"Step4NumHSOff" "Step4NumHSOff"
[19] "Step4ExtOff"


Please, can someone teach me how to create a vector of pairlists ?
I could find no illustrating on-line example.
Thank you very much.
