Dear all, Does anyone know if the PLM package (to run Panel Data Analysis) accepts quarterly data? The package vignette and documentation only use annual data -and the only time index available seems to work for years.

Hola a todos. Estoy atascado en un sitio que no me he encontrado antes, debe ser fácil y rápido, a ver si alguien me puede ayudar. Puesto fácil, tengo: > aa <- matrix(11:19,3,3) > aa [,1] [,2] [,3] [1,] 11 14 17 [2,] 12 15 18 [3,] 13 16 19 Quiero la fila cuyo primer elemento es 12 y el segundo 15. > aa[aa[,1:2] == (c(12,15)),] Error: (subscript) logical

Dear all, Say I have the following dataset: > DF x y z [1] 1 1 1 [2] 2 2 2 [3] 3 3 NA [4] 4 NA 4 [5] NA 5 5 And I want to omit all the rows which have NA, but only in columns X and Y, so that I get: x y z 1 1 1 2 2 2 3 3 NA If I use na.omit(DF), I would delete the row for which z=NA, obtaining thus x y z 1 1 1 2 2 2

Saben si el estimador VARHAC de Den Haan y Levin (1994) ha sido implementado en R? Solamente encontre rutinas para RATS y GAUSS en la pagina de Den Haan. Saludos, Jose Jose Luis Iparraguirre [[alternative HTML version deleted]]

Hola de nuevo: Sigo enfrascado con mi dichoso procedimiento para generar modelos de predicción de series temporales. Llegado un momento pretendo guardar un gráfico en el que se representara: -En a estarán los puntos obtenidos por el alisado (tanto en el pasado como las estimaciones a futuro) -En o estará la serie de datos original. -En inf los limites inferiores de los intervalos de confianza

I have a data table with 712 cases (rows) describing young people’s activities for 72 months each case has been classified into one of 5 clusters. The first 72 columns are monthly activities coded 1 to 6 (e.g. school =1) and the 73rd column is the cluster number of the case. I wish to summarise the distribution of monthly activities by cluster e.g for cluster 1: 6 months school; 24 further

Does anyone know how to retrieve the residuals after running an ERS unit root test on a time series (urca package)? There are no 'residuals' or 'res' (or similar) slots in the ur.ers-class, but a plot instruction - ie plot(ur.ers(....)) renders amongst other things a residual plot. If an augmented Dickey-Fuller test is run, an object of ur.df-class is generated which contains a

I am having difficulty installing the package "lattice". First I tried downloading it from the CRAN site (in the normal way) : the message said it worked but when I typed library I got an error message ("there is no package"). Second I tried installing it from the local zip. I have reproduced the result below. utils:::menuInstallLocal() package 'lattice'

I am using the function prop.test (base package), which returns a list with class "htest". All I want to do is to assign one of its values to a variable, but I do not want R to print the results and added warning message whenever I invoke the function. How can I prevent R from printing on using prop.test? Regards, Jos? Luis Mr Jos? Luis Iparraguirre Senior Research Economist Economic

I could not find a package to run panel data unit root tests in R (there's a STATA module, though - PANELUNIT- and routines for Sarno and Taylor's MADF test, Levin-Lin-Chu's test, Im-Pesaran-Shin's Test, etc, to do this). Hence, I am toying with the idea of having a go at writing up one for R, but would like to know whether anyone is already working on this. José Mr

I have output from a program which produces a distance matrix I want to read into a clustering program in R. The output is a .txt file and is 'almost' lower triangular in the sense that it is just the triangle below the diagonal. So for example a 4-by-4 distance matrix appears as, 1 2 3 4 5 6 i.e. it looks like a lower triangular of a 3-by3. I thought I might be able

Beatriz, Prueba legend("topleft",0,substitute(chi)). En mi PC funciona! En cuanto a LATEX, tienes razón, excede el tema de este foro, con lo que me reservo (lamentablemente) mis sugerencias.

R-helpers I have 120 small Excel sheets to read and I am using library(xlsReadWrite): one example below. I had hoped to read sheets by looping over a list of numbers in their name (eg Book1.xls, Book2.xls, etc). I thought I had seen examples which used eval-parse-paste in this way. However, I have not been able to get it to work.. 1. is this a feasible approach? 2. if not

Dear R users, Consider the first two columns of a data frame like this: > z[,1:2] x y 1 1 1 2 2 2 3 3 3 4 1 4 Imagine that y represents the times that the value x happens in a population. But z is not exactly a frequency table, because in z we have x=1 twice. So, the x=1 in the first line and the x=1 in the fourth are not the same, differing according to a third variable in
