  Dear R-helpers, hello I am seeking your help in somehow getting names of variables without quotes (" "). Let us say, we have a table with 3 variables V1, V2 and V3. After the table is read, I get names of the variables (thro' the following code) as under quotes (like "V1" rather than the original representation V1)  

Dear all   I wish to carry out sigma- and beta-convergence analysis in respect of panel data [wherein current value of one of the variables needs be regressed upon suitably transformed lagged values of another variable(s)]. I am quite new to the R-language and am not very much aware of the availbaility of suitable package(s)/ code in the language. Can any one help me in letting me know of

Dear all, Through the following code, I wanted to perform correlation test repetedly (through loop) on different combinations of variables of a data set. Code: x=read.table("sample.txt",header=T,sep="\t") out="corout.txt" sink(out) nm = names(x) print(nm) nvr=3 # nvr=Total no. of variables in the input data file for (i in 1:(nvr-1)) { for(j in (i+1):nvr) { frm=

Dear all I am intrested in making iterative estimation (thro' loop statements) of, say, linear regression model. For this purpose, I have written the following programme and that I have made use of a sample data (viz., exp.txt): ? Programme: ? # Linear regression modelling with sample data (try5.txt) # Repeated estimation through loop statement
