Could anyone tell me where can I find some examples of the applications to economics of a Markov chain? Many thanks in advance.

Hi, I did not find any web page about using R in economics and econometrics so far. However, this does not mean that there is none (searching with google for "R" and "economics" gives many pages about economics and a name like Firstname R. Lastname on it ;-)). Does anybody in the list does know such a web page? If not, I will be hap...

Dear List, I have a wrapper function that draws a graph that I'd like to use in a vector-like manner. The for-loop version I currently use is below. library(ggplot2) data(economics) h <- 600 w <- 800 #---------------------------------------------------------- draw_metric_by_date <- function( df, i, smooth=FALSE, BASEPATH ) { mlabel <- names(df)[i] qmetric <- qplot( data=df, x=date, y=df[,i], geom=c('line','jitter'), ylab=mlabel...

Dear all, I got point data of trees. I was wondering if anybody has experience in searching the neighbors within a specified distance efficiently. X Y Z 99 34 65 98 35 29 98 34 28 99 33 33 98 32 23 99 33 21 99 33 22 99 32 24 99 30 23 ... What I want to do is : searching for the neighbors with a distance R for each tree & the neighbor must have a bigger Z.

What package/code could I use to create a 3-d surface graph of the predicted values over two of the explanatory variables' coefficients? Jim James Bang Department of Economics University of Illinois Well I AM missing the back of my head.you COULD cut me a little slack! -Homer Simpson

Después del "gather()" puedes hacer un "arrange()" que es una ordenación. Y dentro de "arrange()" le indicas la variable por la que ordenas (no hacen falta comillas)... Lo ordenará alfabéticamente.

No me sale error pero no me imprime la linea, ni ningun gráfico por pais.

Hola usuarios de R Estoy tratando de usar merge, para dos data frame, sin embargo al usarlo me da resultado correcto, en términos de emparejamiento de pais y año, pero lo que me hace es que el dataframe *y* me hace como un append por filas. Las variables comunes son país y año. Alguna sugerencia? combine = merge(sub_kei, knowledge, by = common_col_names, all.x = TRUE, all.y = TRUE) Saludos --

Hola queridos usuarios de R Estoy intentando hacer un gráfico de una variable en el tiempo para un conjunto de países usando R base, con el comando plot. Tengo 40 países y son 15 años.

...he Child Poverty Action Group have written handbooks for benefits advisers which try to specify the system precisely. We'd like to use R for an electronic version of these. I've said quite a bit about R for probing and plotting data. Not only for economists, but for students learning about economics, fiscal policy, and statistics. And after a brief intro to base R, I've concentrated on the Tidyverse, because of what I see as its advantages. There are lots of small demos of the Tidyverse scattered around the web, but fewer of big projects which use lots of different features from it. So my...
