Your description was confusing. You do not have row names that are non-numeric:
> str(dta) 'data.frame': 5 obs. of 5 variables: $ Sub_Pathways: Factor w/ 79 levels "Acetylated_Peptides",..: 3 3 3 3 3 $ BMI_beta : num 0.2382 -0.313 0.1238 0.3035 -0.00982 $ SAT_beta : num -0.0241 -1.9751 0.4095 0.4861 0.3293 $ VAT_beta : num 0.942 -2.22 0.68 0.708 0.016 $ VSR_beta : num 0.2469 -0.2354 0.0554 0.0134 -0.0435 You have a column that is a factor with 79 levels. That cannot be row names because you indicated that the original data was 734*22 dimensions and row names cannot have duplications. If you want numeric values, you need to strip off the first column: > as.matrix(dta[ , -1]) BMI_beta SAT_beta VAT_beta VSR_beta 1 0.23820 -0.02409 0.94180 0.24690 2 -0.31300 -1.97510 -2.22040 -0.23540 3 0.12380 0.40950 0.68050 0.05539 4 0.30350 0.48610 0.70830 0.01337 5 -0.00982 0.32930 0.01597 -0.04353 If you just want to print the character values without quotes: > print(as.matrix(dta), quote=FALSE) Sub_Pathways BMI_beta SAT_beta VAT_beta VSR_beta 1 Alanine_and_Aspartate 0.23820 -0.02409 0.94180 0.24690 2 Alanine_and_Aspartate -0.31300 -1.97510 -2.22040 -0.23540 3 Alanine_and_Aspartate 0.12380 0.40950 0.68050 0.05539 4 Alanine_and_Aspartate 0.30350 0.48610 0.70830 0.01337 5 Alanine_and_Aspartate -0.00982 0.32930 0.01597 -0.04353 But do not forget that they are still character strings. ---------------------------------------- David L Carlson Department of Anthropology Texas A&M University College Station, TX 77843-4352 -----Original Message----- From: R-help [mailto:r-help-boun...@r-project.org] On Behalf Of greg holly Sent: Tuesday, September 19, 2017 10:21 AM To: Duncan Murdoch <murdoch.dun...@gmail.com> Cc: r-help mailing list <r-help@r-project.org> Subject: Re: [R] remove quotes from matrix Dear all; Thanks.
