Hello,
I have an r function that creates the following dataframe tresults2.
Notice that column 1 does not have a column heading.
Tresults2:
[,1]
estparam 18.00000
nullval 20.00000
. . .
ciWidth 2.04622
HalfInterval 1.02311
pertinent code:
results<-cbind( estparam, nullval, t, pv_left, pv_right, pv_two_t,
estse, df, cc, tbox, llim, ulim, ciWidth, HalfInterval)
tresults<-round((results),5)
tresults2<-data.frame(t(tresults))
names(tresults2)<-c("Statistic ", "Value")
tresults2
===========================================================================================
After transposing my dataframe tresults2 consists of 2 columns.
Col1=alphanumeric data (this really is a variable name) and
col2=numeric data (this is value of varaiable).
how do I name columns when columns are different (alphanumeric and numeric)
to avoid the following error:
Error in names(tresults2) <- c("Statistic ", "Value") :
'names' attribute [2] must be the same length as the vector [1]
You tried to give a name to a column that do not exist (the second one you called "value"). You can check that using str(tresults2).
The name of the columns should not (well, I don't see how) interfere with the type (or class) they contain.
You can create a Value column by using tresults2$Value <- your_value
Am I to use c( , ) or list( , ) with a dataframe?
You picked the right one ( c() )... to give the names, I guess this is what you were asking.
Cheers,

Thank you for your help.
