Attach Dataset In R
up Linear Regression in R: “Error in eval(expr, envir, enclos) : object not found” up vote 1 down vote favorite I'm trying to do a simple least-squares regression in R and have been getting errors constantly. This is really frustrating, can anyone point out what I am doing wrong? First I attach the dataset (17 variables, 440 observations, each observation on a object not found r error single line, no column titles). Here, I get a "masked" error. From what I've read, the "masked" error happens when objects overlap. However here I am not using any packages but the default, and I loaded a new workspace image before this. Not sure what this error refers to? > cdi=read.table("APPENC02.txt", header=FALSE) > attach(cdi) The following objects are masked from cdi (position 3): V1, V10, V11, V12, V13, V14, V15, V16, V17, V2, V3, V4, V5, V6, V7, V8, V9 Next, since the data set does not come with headings, I use the colnames() command to add column names, then check my work with the head() command: colnames(cdi)<- c("IDnmbr","Countynm","Stateabv","LandArea","totpop","youngpct","oldpct","actphy","hspbed","srscrime","hsgrad","BAgrad","povpct","unempct","pcincome","totincome","georegion") > head(cdi) IDnmbr Countynm Stateabv LandArea totpop youngpct oldpct actphy hspbed srscrime hsgrad BAgrad povpct unempct pcincome totincome georegion 1 1 Los_Angeles CA 4060 8863164 32.1 9.7 23677 27700 688936 70.0 22.3 11.6 8.0 20786 184230 4 2 2 Cook IL 946 5105067 29.2 12.4 15153 21550 436936 73.4 22.8 11 etcetc(manually truncated) Now the most annoying part: I can't get the lm() function to work! > model1=lm(actphy~totpop) Error in eval(expr, envir, enclos) : object 'actphy' n

Should i define the age? You should read the help page for read.table more thoroughly with particular attention to the `sep` argument. At the moment you have one column in your data.frame. -- David Winsemius, MD West Hartford, CT ______________________________________________ [hidden email] mailing list https://stat.ethz.ch/mailman/listinfo/r-helpPLEAS
