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, Petr Kurtin

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...
