handling a lot of data
...from the file
data without full loading into memory? How can a slower computer with not
enough memory work with such data?
I use the following commands:
data1993 = vector("list", 4);
data1993[[1]] = read.spss(...) # first trimester
data1993[[2]] = read.spss(...) # second trimester
...
data_all = vector("list", 17);
data_all[[1993]] = data1993;
...
and indexing, e.g.: data_all[[1993]][[1]]$DISTRICT, etc.
Thanks,

3D surface plot with wireframe or persp?
...ing for the requirement of "wireframe"
data_for_c = runif(1000,30,85); # range is (30,50)
data_for_s = sort(1/(273+data_for_c));
data_for_time = sort(runif(1000,0,100000)) # range is (0,100000)
data_for_R = exp((-exp(mle_beta0+mle_beta1*data_for_s))*data_for_time)
data_all = cbind(data_for_s,data_for_time,data_for_R)
# function: plot_R_i_3d = f(data_for_time,data_for_s)
plot_R_i_3d = function(data_for_time,data_for_s)
{
R_i = exp((-exp(mle_beta0+mle_beta1*data_for_s))*data_for_time);
return(R_i)
}
# tried 1) persp or 2) wireframe
persp(data_for_time,data...
