using a package function inside another function
Hello all,
I am trying to use the micEcon 'insertRow' function inside a function
I have written. For example:
insert_row_test <- function(m){
insertRow(m,nrow(m)+1,v=0,rName="test")
}
However, when I try to call the 'insert_row_test' function (after
loading the micEcon package), it does not insert a row into the matrix
I pass in. When I call the insertRow

micEcon split into miscTools, micEconAids, and micEcon
The "micEcon" package has been split into three packages: miscTools,
micEconAids, and micEcon.
a) miscTools (version 0.6-0) includes miscellaneous small tools and
utilities that are not related to (micro)economics, e.g. colMedians(),
rowMedians(), insertCol(), insertRow(), vecli(), symMatrix(),
triang(), semidefiniteness(), compPlot(), and rSquared(). The

subsetting a dataframe
How does one remove a column from a data frame when the name of
the column to remove is stored in a variable?
For Example:
colname <- "LOT"
newdf <- subset(olddf,select = - colname)
The above statement will give an error, but thats what I'm trying to
accomplish.
If I had used:
newdf <- subset(olddf,select = - LOT)
then it would have worked, but as I said the column

Maintaining factors when copying from one data frame to another
Greetings all:
OK, this is bugging the @#@%* out of me. I know the answer is simple
and straightforward but for the life of me I cannot find it in the
documentation, in the archives, or in my notes (because I know I've
encountered this in the past). My problem is:
I have a data frame with columns A, B, C, D, and E. A, B, and E are
factors and C and D are numeric. I need a new data frame with

Help with parsing a data file
Hi All,
I need to parse data from a file, example shown below. The first two lines
can be skipped, the third line contains the column names. The next 13 lines
can be skipped. The next line "1991" is a year value, with the following 13
values data for that year. The file then repeats this format with (year, 13
lines of data for that year). I would ideally like to end up with an

extract date time from a text file
I a have a text file where every line is like that:
"2007-12-03 13:50:17 Juan Perez"
("yy-mm-dd hh:mm:ss First Name Second Name")
I would like to make a data frame with two column one for date and the
other one for name.
When I use read.delim it was transformed in a data frame with 4 colums.

Splitting up the micEcon package?
Dear R Users:
The functions of our "micEcon" package [1,2] can be subdivided into three
categories:
- microeconomic demand and firm models
- sample selection models (mainly selection())
- routines for (likelihood) maximisation (e.g. maxLik(), maxNR(), maxBHHH())
(mainly used for ML estimation of sample selection models)
Although sample selection models are often used in

Normalizing grouped data in a data frame
Hi
I am a newbie to R but have tried a number of ways in R to do this and
can't find a good solution. (I could do it out of R in perl or awk but
would like to know how to do this in R).
I have a large data frame 49 variables and 7000 observations however for
simplicity I can express it in the following data frame
Base, Image, LVEF, ES_Time
A, 1, 4.32, 0.89

R:Maximum likelihood estimation using BHHH and BFGS

I am new to R. I would like to find *maximum likelihood estimators for psi

Inserting a new row in a matrix
Hi guys,
I need to insert a row to a matrix in a for loop. I have matrix named "Avg"
which is a 5x4 matrix of zeros.
I have a file named "A"(4 rows,14 columns) which I make a sample of it 5
times. each time I get the mean for each column and put the result in the
"Avg" matrix. this is my code:

How to return individual equation from {aidsEst} in package [micEcon]?
Hi, R core team
I am using the function {aidsEst} in package [micEcon] to do an AIDS
model now. So far, everything is good. But I want to test the auto
correlation and heteroskedasticity of the individual equation from AIDS
demand system. How can I return the individual equation?
PS: serial correlation test is {bgtest} in package [lmtest] and
heteroskedasticity is {bptest} in package

since nobody answered to my first message, I try to explain my problem more

Therefore, I would like to avoid to describe all variables in the "\format"

heckit / tobit estimation
Dear All,
we (Ott Toomet and I) would like to add functions for maximum likelihood (ML)
estimations of generalized tobit models of type 2 and type 5 (*see below) in
my R package for microeconomic analysis "micEcon". So far we have called
these functions "tobit2( )" and "tobit5( )".
Are these classifications well known? How are these functions called in other

Using data frames for EDA: Insert, Change name, delete columns? (Newcomer's question)
I am finding complex analyses easier than some elementary operations in
R. In particular I want to do some low level exploratory data analyses
with data in a data frame but cannot find commands to easily insert,
remove (delete), rename, and re-order (arbitrarily, not sort) columns.
I see that the micEcon package has an insertCol command, but that is for
matrices, not data frames. I have looked

Heckman regression / adjustment for standard errors?
Hello folks,
I am trying to estimate the two-step Heckman regression model. I would like to make an adjustment for intragroup correlations. Stata can implement this with the "cluster" option, but I am really hoping to stick with R. It seems that the micEcon package is the primary source for this two-step regression model (i.e., heckit), but I can't find a way to make the

AIC for heckit
Hi,
I have used the heckit function in micEcon. Now I
would like to evaluate the fit of the probit part of
the model but when I enter

I get this error
Error in logLik(object) : no applicable method for

How can I then get the AIC for this model?
