[R] problem with accents and Catalan characters (for ex. ç) using geocode function (ggmap)

Dear all, I'm trying to geocode addresses (of Catalonia) with accents and Catalan characters (as for example "ç"). I'm using the "geocode" function (package ggmap), but I obtain some Google "INVALID_REQUEST" when the addresses have these characters. For example: > geocode("Carrer Veneçuela, 10,

[R] A vector of normal distributed values with a sum-to-zero constraint

Dear all, Anyone knows how to generate a vector of Normal distributed values (for example N(0,0.5)), but with a sum-to-zero constraint?? The sum would be exactly zero, without decimals. I made some attempts: > l <- 100 > aux <- rnorm(l,0,0.5) > s <- sum(aux)/l > aux2 <- aux-s > sum(aux2) [1

Re: [R] if(...){next} with "foreach" loop?

You are absolutly right! I can use If(!cond) inside the loop. Thank you! 2014-02-11 12:43 GMT+01:00 Duncan Murdoch : > On 14-02-11 5:30 AM, Marc Marí Dell'Olmo wrote: > >> Dear all, >> >> I want to do a loop with foreach. But, I would like to include a condition

[R] if(...){next} with "foreach" loop?

Dear all, I want to do a loop with foreach. But, I would like to include a condition with "next" to don't loop over some elements. For example, I would like to translate this "for loop" to a "foreach loop": for (i in 1:10) { for (j in 1:2) { ... if((i==2 & j==1) | (i==4 & j==3)) { next }

[R] convert point coordinates UTM to WSG

Dear R-users, Can anyone tell me how to convert point coordinates from WSG84 (google maps coordinates) format to UTM HUSO-31 ED-50. And if I have a map (shp format) with UTM HUSO-31 ED-50 coordinates, how can I convert to WSG84 (google maps coordinates) coordinates. Should I install some external

[R] Functions in R like lincom and nlcom of Stata

Hello all, Does anyone know if there exists any function in R that resembles the "lincom" and "nlcom" of STATA?. These functions computes point estimates, standard errors, significance levels, confidence intervals, etc. for linear and non linear combinations of previous estimated parameters. Down
