How to specify ff object filepaths when reading a CSV file into a ff data frame.
Really old subject?, so, all my apologizes for digging up
but, since I also ran into this? maybe this hack can be useful to someone
I propose monkey patching here:
library(ff)
my.as.ffdf.data.frame <- function (x, vmode = NULL, col_args = list(), ...)
{
rnam <- attr(x, "row.names")
if (is.integer(rnam)) {
if (all(rnam == seq_along(rnam)))
rnam <- NULL
else rnam <- as.character(rnam)
}
x <- as.list(x)
vmodes <- vector("list", length(x))
if (!is.null(vmode)) {
nam <- names(x)
if (is.list(vmode)...

Coerce rectangular matrix to symmetrical square matrix
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
I have a rectangular matrix of size 920 by 85. I'd like to coerce it into a
square matrix such that all row/col names are present in the new matrix and the
additional values are zero.
As an example:
A B C D
A 1 2 3 4
E 5 6 7 8
F 9 10 11 12
Would be coerced to:
A B C D E F
A 1 2 3 4 5 9
B 2 0 0 0 6 10
C 3 0 0

aregImpute in Hmisc
...dataframe ds1.2 - 503 categorial variables
and 1 continuous response variables. I ran aregImpute
to deal with NA's and got the followig error:
> fmla = terms( Response ~ . ,data=ds1.2)
> ds.i = aregImpute(fmla,data=ds1.2)
Error in matrix(as.double(1), nrow = n, ncol = p,
dimnames = list(rnam, :
length of dimnames [2] not equal to array
extent
Could you explain what I should do? Thanks a lot.

Error messages with psm and not cph in Hmisc
...nt","contr.treatment"))
the equivalent
sm4.6ll<-fit.mult.impute(Surv(agesi, si)~partner+ in.love+ pubty+ FPA+
strat(gender),fitter = *psm*, xtrans = dated.sexrisk2.i, data =
dated.sexrisk2, x=T,y=T,surv=T, time.inc=16)
returns the error message
Error in dimnames(X) <- list(rnam, c("(Intercept)", atr$colnames)) :
length of 'dimnames' [2] not equal to array extent
Using survreg{survival} for which psm is a wrapper, also runs perfectly on
the unimputed dataset.
Is this a bug, or am I doing something wrong? I particularly want to make
use of Design'...
