Can't Load Text Files
Hi,
I've completely forgotten how to do R, and it seems I can't even load
simple files correctly.
I have two tab deliminated text files (attached, these were test files
of the larger data files I'm trying to work with) that I am trying to
load into R so that I can merge them. They were originally excel files
but I used "saved as" to reformat to text. I don't know if

Can R fill in missing values?
Hi,
I know this can be done in Stata (which is quite messy) but I wanted to
know if it can be done in R. So lets say I have a merged data set (I
used the merge function by date for the attached two files), where all
the missing values are filled with NAs (which is what the all.x=TRUE does).
Is there any way to replace those NAs with the value of the latest row
that contains a value?

Marking Interval Length
Hi everyone,
I'm trying to break down data into intervals because I need to analyze
data according to the intervals between each change in value. What I
have done is merged the attached data files, and filled in the missing
values this way:
> fmt<-"%m/%d/%y"
> dd<-read.csv("Desktop/R/CDSdate.txt")
> dd$Date<-as.Date(dd$Date, fmt)

Rearranging Data
Hi everyone,
A few days back Jim helped with out, helping me find an automated way of
determining the mean and median of intervals between price changes.
However, a new set of data I have is no longer in the same format.
CDSmod is the file that was used with this code:
x <- read.csv('/cdsmod.csv', as.is=TRUE, check.names=FALSE)
x$Date <- as.Date(x$Date, "%m/%d/%Y")

Can we disable secondary_bus_reset in runtime?
I think we need this feature at least for debugging purpose, right?
Or, do we already have this feature?
Thanks,

Invalid VA => ptr conversion with xc_dom_* API after XSA-55 fox
Hi list,
Jeff and FastIce pointed out a regression between Xen 4.1.2 and 4.1.6
when starting NetBSD domU; the kernel syms table gets slightly corrupted
[1].
After dwelling into libxc code, FastIce noticed that changing back the
return value to "ptr + offset" (instead of just "ptr") for
xc_dom_vaddr_to_ptr() makes it work again.
According to [2] while fixing XSA-55, Ian

How to plot 2 continous variables on double y-axis with 2 factors: ggplot2, gplot, lattice, sciplot?
Hi,
I have a data set with two continous variables that I want to plot MEANS (I
am not intrerested in median values) on a double-y graph. I also have 2
factors. I want the factor combinations plotted in different panes.
Dummy dataset:
mydata <- data.frame(factor1 = factor(rep(LETTERS[1:3], each = 40)),
factor2 = factor(rep(c(1:4), each = 10)),

Plotting an interaction with error bars
Hello.
I need to plot a two-way interaction (5 levels X 3) with error bars.
The x.factor will be the five-levels var and the trace.factor will be
the three level var.
I was able to find functions that draw error bars, but still couldn't
find a way to draw an interaction plot that looks like what is common
in psychological (and related) journals: the lines (three in my need)
are plotted in

Wbinfo -Y couldn't work with idmap_rid for BUILTIN groups
Hi,
wbinfo -Y BUILTIN\group can work without idmap_rid in Samba-3.0.14a. But
I'm experiencing wbinfo -Y with idmap_rid failed for SID to GID
conversion of BUILTIN groups.
Since idmap_rid only works in a single domain, and captures workgroup's
domain sid as a real domain sid in rid_idmap_get_domains(), when running
"wbinfo -Y BUILTIN/System Operators", the function

means and variances of several groups in the matrix
Dear R users,
I have 32 observations in data x. After sorting this, I want to compute
means and variances of 3 groups divided by "nr".
Actually, the number of groups is flexible. Any suggestion will be greatly
appreciated.
