Dear Colleagues, I have a dataframe with variables:
[1] "ID" "category" "a11" "a12" "a13" "a21" [7] "a22" "a23" "a31" "a32" "b11" "b12" [13] "b13" "b21" "b31" "b32" "b33" "b41" [19] "b42" "c11" "c12" "c21" "c22" "c23" [25] "c31" "c32" "c33" "d11" "d12" "d13" [31] "d14" "d21" "d22" "d23" "d24" "d25" [37] "d31" "d32" "d33" "e11" "e12" "e13" [43] "e21" "e22" "e23" "e31" "e32" "e33" [49] "f11" "f12" "f13" "f14" "f21" "f22" [55] "f23" "f24" "g11" "g12" "g13" "g14" [61] "g21" "g22" "g23" "g24" "g31" "g32" [67] "g33" "g41" "g42" "g43" "h11" "h12" [73] "h13" "h21" "h22" "h23" "C1.Employ" "SC11.Ops" [79] "SC12.Unit" "SC13.Nonadvers" "C2.Enterprise" "SC21.Structure" "SC22.Gov" "SC23.Culture" [85] "SC24.Stratcomm" "C3.Manage" "SC31.Resource" "SC32.Change" "SC33.Continue" "C4.Stratthink" [91] "SC41.Vision" "SC42.Decision" "SC43.Adapt" "C5.Lead" "SC51.Develop" "SC52.Care" [97] "SC53.Diversity" "C6.Foster" "SC61.Teams" "SC62.Negotiate" "C7.Embody" "SC71.Ethical" [103] "SC72.Follower" "SC73.Warrior" "SC74.Develop" "C8.Comm" "C81.Speak" "C82.Listen" [109] "OverallImp" The variable "category" has four values: Regular, CCM, CFM, and Other I'd like to create a table like this to feed into barplot2: row.name C1.Employ C2.Enterprise C3.Manage C4.Stratthink C5.Lead C6.Foster C7.Embody C8.Comm Regular 3.68 4.27 3.22 etc...... CCM 4.32 4.56 etc..... CFM etc......... Other etc......... So far, I have been able to get this far: > mean(subset(impchiefs08,category=="Regular",select=c(C1.Employ,C2.Enterprise,C3.Manage,C4.Stratthink,C5.Lead,C6.Foster,C7.Embody,C8.Comm ))) C1.Employ C2.Enterprise C3.Manage C4.Stratthink C5.Lead C6.Foster C7.Embody C8.Comm 3.600000 3.851111 4.482222 4.346667 4.608889 4.444444 4.602222 4.493333 > But I am stumped as to how to get what I want.
