[R] Clustered Standard Errors?

Hi, I found this post from 2011 for doing clustered standard errors in R. Is there any update to the lm package that allows to do this without having to write your own function? In STATA is as simple as adding cluster to

[R] R package with Fortran module on Windows? undefined reference to `__stack_chk_fail'

Hi, I created a R library that uses a Fortran module. Everything works like a charm on linux. Now I'm trying to make it work on Windows. I cloned my git repository on a windows computer, and when I press the build and reload button on Rstudio I get these errors

[R] Speeding up code?

Hi R-Help! I'm hoping that some of you may give me some tips that could make my code more efficient. More precisely, I would like to make the answer to my stakoverflow question more efficient

Re: [R] ivreg with fixed effect in R?

Thanks. One more question. When I do summary to see the coefficients how can i tell R to print just some of the coefficients? Thanks again On Sat, Oct 19, 2013 at 7:29 AM, Achim Zeileis wrote: > On Sat, 19 Oct 2013, Ignacio Martinez wrote: > > I want to estimate the following fix

[R] ivreg with fixed effect in R?

I want to estimate the following fixed effect model: y_i,t = alpha_i + beta_1 x1_t + beta_2 x2_i,tx2_i,t = gamma_i + gamma_1 x1_t + gamma_2 Z1_i + gamma_3 Z2_i I can use ivreg from AER to do the iv regression. fm <- ivreg(y_i,t ~ x1_t + x2_i,t |x1_t + Z1_i + Z2_i, data = Da

[R] lapply to multivariate function?

I have a Data Frame that contains, between other things, the following fields: userX, Time1, Time2, Time3. The number of observations is 2000. I have a function that has as inputs userX, Time1, Time2, Time3 and return a data frame with 1 observation and 19 variables. I want to apply that function

[R] Finding a max

My data looks like this: X Y1(X) Y2(X) i want to find the values of x that maximize Y1 and Y2. Right now I'm getting the answer but I would like to know if there is a more efficient/elegant way of doing this. This code reproduces what I'm doing: [code] prop3<-structure(list(effort = c(0, 0.00898

[R] Plot 3 lines in one graph

I'm new with R. I want to plot 3 lines in one graph. This is my data: print(x) V1 V2 V3 V41 -4800 25195.73 7415.219 7264.282 -2800 15195.73 5415.219 7264.28 I tried using matplot, but I cannot get exactly what I want. This is what I get, and this is my code: matplot(x[,1],x
