Hola, Tengo la base de datos de un censo agropecuario el cual está en formato de SPSS, cuando cuando ejecuto el comando para introducirlo a R, despues de permanecer lento R, aparece esto: Error: cannot allocate vector of size 1.6 Mb Hasta aquí llega y no introduce ninguna observación. Mi pregunta es si existe alguna solución, talvez aumentar la memoria de R?? Imagino que como ustedes han

Dear All, I've tried to sum columns -- different species of flowers, fruits plus twigs -- with NAs to get litterfall/trap, and then after use litterfall to calculate production (litterfall (grams)/ hectare/ day. But R 'sees' litterfall/trap as a string. My question: How to use basic mathematical functions to deal with NAs in data management. Example (as you can note I have many

Dear All, I have tried to calculate tree mean growth but I think the structure I used below (growthresumo) is not the most elegant, even though it worked. The only problem I had in this first part was that I cannot use 'summary', just 'mean' (sorry but 'R' is pretty new for me). >growthresumo <-

Dear All, I created a script to calculate averages - two groups: "parcel" and "date" - and, based on these averages, make a graph. The problem is that 'R' does not recognize the first column even if I try to insert one. A brief example Raw data: Data <- sample(1:100, 30, replace = FALSE, prob = NULL) Date <-

Estimados usuarios de R: Estoy probando la econometría espacial reproduciendo el paper Introduction to Spatial Econometrics: An application to the study of fertility in Argentina using R. de Herrera Gómez, Marcos; Cid , Juan Carlos and Paz , Jorge Augusto. La diferencia es que voy a usar datos de Uruguay del Censo 2011. Ellos utilizan GeoDaSpace para calcular la matriz de contigüidad (tambien

Hola, Yo en vez de data.table, probaría con el paquete "*sqldf*" que tiene una sintaxis en sus queries más sencilla que la de data.table. Y en términos de volumen [1] y velocidad [2] de respuesta son bastante equivalentes.

I feel like Marlon Brando in "On the Waterfront" where he's told "It's not your night, kid", except for me it has been the last two months trying to debug memory problems. Now I can't even install an old version of this package on a netbook running the Ubuntu 10.10 netbook remix because it can't find the libraries libf77blas and libatlas. I have even gone to

Dear R-helpers, We marked 6000 leaves from 5 SPECIES - 10 individuals/species - in two different TREATMENTs: a control and a dry-plot from which 50% of incoming precipitation was excluded. We followed those leaves for 42 months and noted the presence and absence at each visit. I then carried out a Cox Harzard model to see differences in leaf mortality between parcels and among species over time:

Hola a todos, Estoy intentando realizar un análisis de medidas repetidas en R y me gustaría pediros opinión porque estoy un poco atascada. Estoy utilizando las funciones lme y lmer.

Hi everybody, I need to know about sound quailty issues from those who have experience with Tormenta2 PRI Interface. Also how to make it work with new versions of Asterisk and Zaptel. And also suggestion if it is a good idea to switch to some newer card from Sangoma or Digium, or Tormenta should work fine. I have sound breaking many times a day over the trunks.

Estimados Escribo para consultar sobre el uso de modelos mixtos anidados. Los datos que estoy analizando provienen de censos de malezas en cuatro tipos de paisajes de la región pampeana, en los que seleccioné al azar igual número de lotes agrícolas cultivados con tres cultivos (maíz, soja y trigo-soja). En cada lote censé el número de especies de malezas en tres posiciones: el alambrado, el borde

... and the mailing list is picky about attachments... whatever you attached did not conform to the stringent requirements mentioned in the Posting Guide. Pasting the code right into the email is usually safest, though you DO have to post using plain text (as the Posting Guide indicates) or your code may get mangled by the automatic html format removal.

OK, Let's try this again! Here is the reproducible script; it is long because I had to copy the panel dataset here. My question is related to systemfit; I don't know how to get the result for the entire panel. #Reproducible script Empdata<- read.csv("/Users/ngwinuiazenui/Documents/UPLOADemp.csv") View(Empdata) install.packages("systemfit")

Sadly you failed to set your email program to send plain text and the data is corrupted at my end. I also think you need to reduce the size of the data set... the intent here is to increase your understanding, not debug your particular analysis. I will say that I am having a very challenging time understanding what you are trying to accomplish though. What are the equations that you think need
