Step 1:I have a simplified dataframe like this: df1 = data.frame (B=c(1,0,1), C=c(1,1,0) , D=c(1,0,1), E=c(1,1,0), F=c(0,0,1)
I know that I can change a data.frame column name by: colnames(df)[3] <- \"newname\" But there might be cases where the column I want to change is not in the 3rd position. Is there a way to look
I\'m an R newbie and I\'m trying to understand the xyplot function in lattice. I have a dataframe: df <- data.frame(Mean=as.vector(abc), Cycle=seq_len(nrow(abc)), Sample=rep(colnames(abc), each=
I have two large data frames, a and b for which identical(a,b) is TRUE, as is all.equal(a,b), but identical(digest(a),digest(b)) is FALSE.What could cause this?
I have a data frame and I\'开发者_如何学Pythonm trying to run a subset on it. In my data frame, I have a column called \"start\" and I\'m trying to do this:
After I\'m done with some manipulation in Dataframe, I got a result dataframe. But the index are not listed properly as below.
I know there is an easy way to do this...but, I can\'t figure it out. I have a dataframe in my R script that looks something like this:
I have a question about modifying a matrix. I have managed to change values in a matrix depending on the value
I have a for loop, which returns me values from one dataframe using which, which.min and which.max giving me the \"coordinates\". Here an example
I want to append or add a data.frame to itself... Much in the same way the one adds: n <- n + t I have a function that 开发者_如何学运维creates a data.frame.
