r - Creating a list/vector from first column od multiple data -

-

in total have 21 csv files load r. did:

list_of_data = list.files(pattern="*.csv") tbl_met = lapply(list_of_data, read.csv)

can't give dput because it's data...

what want list off names in first column in datasets. combined 1 vector/list there 2 problems:

  • first of columns in files separated ";" or without separation mark... have inside files , make them separated in same way ?

  • second problem there might duplicates of names , i'd remove them list.

do have idea how ? should provide more data ? if yes, let me know how that.

i found solution. it's not easiest 1 works. first of had convert of csv files same pattern. easy task r.

later:

list_of_data = list.files(pattern="*.csv") tbl_met = lapply(list_of_data, read.csv) tbl <- rbindlist(tbl_met) ## binding of tables in list row  vec_names <- tbl$locus ## name of column names interested in vec <- unique(vec_names) ## removing duplicates

nicely done!

i'm trying plot frequency characteristic equation using ezplot, matlab gives following warning, "contour not rendered non-finite zdata". have used command plot frequency equations warning , plot display empty , not change axis range well. can please help. appreciated. here's code i'm using. % transfer matrix case-i, thin rotor clear all; clc; ei = 1626; l = 0.15; m = 0.44108; = 2.178*10^-4; i_p = 2.205*10^-5; itr = 0.24; i_pr = 0.479; syms p n; f = [1 l*1i l^2/(2*ei)*1i l^3/(6*ei); 0 1 l/ei -l^2/(2*ei)*1i; 0 0 1 -l*1i; 0 0 0 l]; p = [ 1 0 0 0; 0 1 0 0; 0 -it*p^2+i_p*n*p 1 0; -m*p^2 0 0 1]; p_r = [1 0 0 0; 0 1 0 0; 0 -itr*p^2+i_pr*n*p 1 0; -m*p^2 0 0 1]; = f*p*f*p*f*p*f; b = p_r*f*p*f*p*f; r = a(1,2)/a(1,4); a12_p = 0; a22_p = a(2,2)-r*a(2,4); a32_p = a(3,2)-r*a(3,4); a42_p = a(4,2)-r*a(4,4); ap(2,2) = a22_p; ap(3,2) = a32_p; ap(4,2) = a42_p; ap(4,4) = 1; c = b*ap; m = [c(3,2) c(3,4); c(4,2) c(4,...
