Probit cluster-robust standard errors
If I wanted to fit a logit model and account for clustering of observations, I would do something like:
library(Design)
f <- lrm(Y1 ~ X1 + X2, x=TRUE, y=TRUE, data=d)
g <- robcov(f, d$st.year)
What would I do if I wanted to do the same thing with a probit model?
?robcov says the input model must come from the Design package, but the Design package appears not to do probit?
Thanks very

Excuse me
Dear R software faculty:
There is a question bothering me. That is why we can not set the property of row.names=false when we output csv data. But there exists that parameter in R help. Hoping for your reply!

ggplot2 dot chart-start at zero
I am trying to create a simple dot-plot in ggplot2 with a solid line from the y-axis to the dot, something I first saw in Cleveland's 1984 book
What I would like is to have the graph start at zero on the x-axis but leave some space on the right side of the plot area.
I assumed that I should be able to do this with expand() in scale_x_continuous() but either I'm wrong or just don't

How to do the same thing for all levels of a column?
Dear all,
I am a R beginner, and I am looking for a way to do the same thing for all

Basically, I have a bunch of protein sequences composed of different amino
acid residues, and each residue is represented by an uppercase letter. I

Canadian politcal party colours in ggplot2
A stupid question but does anyone know how to express the actual colours used by the main Canadian political parties? I want to do a couple of ggplot2 plots and have lines or rectangles that accurately reflect the party colours.
I can probably play around with RColorBrewer or something to figure it out but if some some already has got them it would save me some time especially with the NDP

Problems with Linksys IP Phone SPA 942
Hi people,
I'm having problems of connection with a Linksys SPA IP PHONE 942 when I use the WAN port, most of the time when I try to connect to the network or restart the IP Phone I can't get internet connectivity . I tried using both static IP and DHCP, but the problem is the same. Some have had similar problem with this brand of IP Phone?
Thanks for the help and attention.

quote a column of a dataframe by its name
Dear All,
I have a question, suppose X is a dataframe, with column names as
"x1", "x2", "x3", ..... And I would like to use the i-th column by X[,'xi'].
But it seems the single quote and double quote are different.
So if I run X[, names(X)[i]], it has some error.
Please use the below example code
X = matrix(rnorm(50),ncol = 5)
X = data.frame(X)
