...mbers into a second data frame and skips the rows that contain a single NA value. I want to know if there is a simple way to determine if a row (about 20 columns) contains a single NA value without running a loop that checks each individual cell.

...ng a name with a string variable and using the string variable to create a data frame (or any object) whose name is the string value of the variable and 2) pass on a string to a function as a parameter, and then use that string to refer to an existing data frame.

...ow 7, but the row name is still "8". I have figured out how to assign a sequence vector to the row names, but I am wondering if there is a built-in command that does the same thing. (I.e., change the name of row 7 to "7" from "8".) Thank you very much.

...n model.frame.default(formula = respmat ~ predmat, data = inputmat) : invalid type (list) for variable ''respmat'' I happen to have a lot of NAs in some of the columns. Is that the problem? Any input will be greatly appreciated. Thank you very much, in advance.

...6 graphs consisting of exactly the same plot for 6 different groups. I would like to add one title for the entire figure at the top of the figure, but I cannot figure out how to do that without anchoring the title one of the graphs. Is it possible to do that?

Hi, I have written boxplot commands of this form before, but I don''t quite understand why the function call is reporting a syntax error in this instance. All parameters passed to the function are strings. Thanks in advance. Payam > simplevar <- function(wframe,column1,column2) { + tframe <- get(wframe) + x1 <- which(names(wframe)==column1) + x2 <-

I have encountered a more fundamental problem in my data set. I''m using read.csv, and all the data are imported as character. How do I do a string comparison in a line like this: M10[ !sapply(1:10, function(x)666 %in% M10[x,]), ] Alternately, how do I change the class type on a column in a data frame from character to numeric? Thank you very much. Payam [[alternative HTML version

Hello all, It seems that the GeneMeta passage returns NA in the respective row if any gene in the data sets to be synthesised are missing. Do you know of a way to overcome this problem? I tried using the 'impute' package to fill-in the missing values, but R crashes if 'impute' and 'GeneMeta' packages are used together. I have asked a separate question for that. Thanks

With apologies if I missed the answer in the response given to my previous question. How do I extract the name of an object and assign it to a string variable? For example, I have a dataframe named comnoglyc How do I assign this name to a variable dfname such that print(dfname) returns "comnoglyc"? Thank you very much.
