[R] write out list of lists with names

Hello List

I have a list question. I'm doing some data wrangling for a colleague and I
have nested list in the following format:

structure(list(MU10 = structure(c(0.80527905920989, 0.4350488707836, 
0.455195366623, 0.565174432205497, 0.208180556861924), .Names =
c("MU.16",
"MU.19", "MU.21", "mean", "sd")), MU11 =
structure(c(0.56061565798878,
0.65200918021661, 0.606312419102695, 0.0646249793238221), .Names =
c("MU.21",
"MU.22", "mean", "sd")), MU12 =
structure(c(0.77265115449472,
0.3925776107826, 0.38222435807226, 0.515817707783193, 0.222484520748552
), .Names = c("MU.14", "MU.20", "MU.23",
"mean", "sd")), MU13 = structure(c(0.36360576458114,
0.21396125968483, 0.288783512132985, 0.105814644179484), .Names =
c("MU.20",
"MU.22", "mean", "sd")), MU14 =
structure(c(0.31692017862428,
0.31692017862428, NA), .Names = c("MU.18", "mean",
"sd")), MU15 = structure(c(0.57645424339545,
0.82369227173036, 0.700073257562905, 0.174823686402807), .Names =
c("MU.18",
"MU.22", "mean", "sd"))), .Names =
c("MU10", "MU11", "MU12",
"MU13", "MU14", "MU15"))

I would like to write this to a text file in the form e.g. (each x is a value):

MU10
MU.16? MU.19? MU.21? mean? sd
x? x? x? x? x? 
MU11
MU.21? MU.22 mean sd
x? x? x? x

Where each list element is on a new block of three rows.

After consulting Google I came across the following:

fnlist <- function(x, fil){ 
z <- deparse(substitute(x))
cat(z, "\n", file = fil)
nams <- names(x)

for (i in seq_along(x) ){ cat(nams[i], "\n", x[[i]],
"\n",file = fil, append = TRUE) }
}

fnlist(holdList, 'res.txt')

However this doesn't print the names within each sub list.

Can anyone advise?

Thanks

Iain

[R] write out list of lists with names

Here is one way using capture.output and regular expressions
> cc <- capture.output(ll) ## ll is your list object
> kk <- cc[cc!= ""] ## remove blank lines
> kk <- gsub("\\$", "", kk) ## remove '$' from
names

Hello List

I have a list question. I'm doing some data wrangling for a colleague and I
have nested list in the following format:

structure(list(MU10 = structure(c(0.80527905920989, 0.4350488707836, 
0.455195366623, 0.565174432205497, 0.208180556861924), .Names =
c("MU.16",
"MU.19", "MU.21", "mean", "sd")), MU11 =
structure(c(0.56061565798878,
0.65200918021661, 0.606312419102695, 0.0646249793238221), .Names =
c("MU.21",
"MU.22", "mean", "sd")), MU12 =
structure(c(0.77265115449472,
0.3925776107826, 0.38222435807226, 0.515817707783193, 0.222484520748552
), .Names = c("MU.14", "MU.20", "MU.23",
"mean", "sd")), MU13 = structure(c(0.36360576458114,
0.21396125968483, 0.288783512132985, 0.105814644179484), .Names =
c("MU.20",
"MU.22", "mean", "sd")), MU14 =
structure(c(0.31692017862428,
0.31692017862428, NA), .Names = c("MU.18", "mean",
"sd")), MU15 = structure(c(0.57645424339545,
0.82369227173036, 0.700073257562905, 0.174823686402807), .Names =
c("MU.18",
"MU.22", "mean", "sd"))), .Names =
c("MU10", "MU11", "MU12",
"MU13", "MU14", "MU15"))

I would like to write this to a text file in the form e.g. (each x is a value):

MU10
MU.16? MU.19? MU.21? mean? sd
x? x? x? x? x? 
MU11
MU.21? MU.22 mean sd
x? x? x? x

Where each list element is on a new block of three rows.

After consulting Google I came across the following:

fnlist <- function(x, fil){ 
z <- deparse(substitute(x))
cat(z, "\n", file = fil)
nams <- names(x)

for (i in seq_along(x) ){ cat(nams[i], "\n", x[[i]],
"\n",file = fil, append = TRUE) }
}

fnlist(holdList, 'res.txt')

However this doesn't print the names within each sub list.

Can anyone advise?

Thanks
