Hi is there any command or setting that allows you to do the plot command but it dose not print the plot on screen? So when you are saveing an plot in a function you dont want it to display the plot just save it. -- View this message in context: http://r.789695.n4.nabble.com/Dont-print-plot-on-screen-tp3078167p3078167.html Sent from the R help mailing list archive at Nabble.com.

It looks from str(SA) that Response IPS1 is a data.frame of class "anova", which probably cannot be coerced to vector. Maybe you can use unlist() instead of as.vector() Or something like SA[["Response IPS1"]]["as.factor(WSD)",] ## to select the first row only, even maybe with unlist() Without a better REPRODUCIBLE example, I cannot tell more (maybe some others

Dear All If I have the following dataset V1 V2 x y y x z b a c b j d l c o How do I use R command to get the total number of different letter in column "V1" column "V1" has 7 different letters.

Dear users, I have looked on different sources and found different functions to prompt the user to provide input. However, I couldn't find one that does exactly what I'm looking for. select.list() and menu() are nice because a graphic window appears to prompt the user. However, the user can only choose from a predefined list of choices. readline() and scan() are more free in the

Hi. In a data set I have a variable that takes values from 1 to 14. For each subgroup of values of this variable, I would like to obtain some descriptive statistics of other variables present in the data set. I've been trying with a "for" loop but I couldn't get nothing. Could you please suggest me some lines? -- View this message in context:

Dear All, Can you please suggest me a correct way to load the following R data frame from the internet and save it to the hard drive? The following is what I tried: > raceprofiling <- > read.table("http://rss.acs.unt.edu/Rdoc/library/twang/data/raceprofiling.RData") > save(raceprofiling, file = 'raceprofiling.RData') However, when I used dim() to check the dataset,

Hi, I'm running R 2.11 Does anyone know if it possible to transform one character vector to one character string ?

Dear all, how can I perform a string operation like strsplit(x," ") on a column of a dataframe, and put the first or the second item of the split into a new dataframe column? (so that on each row it is consistent) Thanks Boris

Hi R users I have these two vectors: Row <- sample(1:25, 10) Col <- sample(1:25, 10) Is there a way to combine them into a list, whose first component is a vector containing the first element of Row and the first element of Col, the second component is a vector containing the second element of Row and the second element of Col, and so on... Thanks you Lorenzo

Dear R helpers I seem to have one trivial problem but can't find solution to it. Suppose I have following input. A = c(1,  3,  0,  5,  8)                  # 3rd element is 0 B = c(100, 30,  0,  25,  40)          # 3rd element is 0 C = A/B > C [1] 0.01 0.10  NaN 0.20 0.20 Obviously, I can't divide 0/0 and hence NaN. My problem is how to replace this NaN say by 0. So that I can

Dear R experts, I've written some functions in a few source files (such as main.R, control.R ...). After loading them into R, how do I retrieve which functions are loaded from which source file? For example: main.R has functions: myPrint(), myScan() control.R has functions: setPrinter(), setData() After loading the sources (main.R and control.R) into R, I would want to know that

Dear R helpers Suppose val1 = c(10, 20, 35, 80, 12) val2 = c(3, 8, 11, 7) I want to select either val1 or val2 depending on value of third quantity val3. val3 assumes either of the values "Monthly" or "Yearly". If val3 = "Monthly", then val = val1 and if val3 = "Yearly", then val = val2. I tried the ifelse statement as ifelse(val3 =

Hello, I'd like to ask you something again. I have a database and it has a column which looks like this one here: small_factor <- factor(c("d_variable1","d_variable2","d_variable3")) small_factor Now the thing is that I would like to convert each element of this factorized column. Basically I want to rewrite the words in it without the first two characters:

Hi all, I generally use the Reduce() function to reduce the dimension of list object. However in my current session I have few objects which are actually list of list of list..(say n step). If I reduce their dimension then I have call Reduce() function many times. Therefore my question is, is there any 1-step way to reduce the dimension at the lowest level? Take this example: lis1 <-

Dear collegues! Given a matrix, I would like to remove columns, that do not fulfill a certain condition. The condition is, that the median of the column is higher than a certain value. I've seen the help on removing NA columns, but I cannot figure out how to change the function part of the statement, so that the function is only TRUE if the median of the column is higher than x;

Dear R-Users, I have a trivial problem, but extensive googling and ??'ing did not solve it: I want to obtain the sums of squares from a summary.aov() object for later use. Example: > DV <- rnorm(100) > IV1 <- as.factor(rep(c("male", "female"), times = 50)) > IV2 <- as.factor(rep(c("young", "old"), times = 50)) > >

Hi, What is an efficient way to take this DF data.frame(A=c(1,2,NA,NA),B=c(1,NA,NA,4)) and get c(NA,"TWO","BOTH","ONE") as the result, where NA corresponds to a row without "NA"s, TWO indicates NA in the second and ONE in the first column. Thanks for any pointers. Joh

Hi All, Is it possible to use the subset() function to select data based on multiple values of a single variable from a data frame. My actual data set is much bigger and would like to illustrate with following dataset > df = data.frame(x = c('a','b','c','d','e','f','g','h','a','a','b','b'), y =

Dear all, i have spent a lot of time trying to solve this problem, but I am sure that there must be a simple solution. So, as a last resort, I am coming back to you again. I have a dataset with some (almost random) values in many variables. Lets say that the dataset represents the scores of students to test questions. What I need to do is to sum the scores for each student. However, wherever

I have a dataframe with columns "ID",'date","estimate","actual" (but not necessarily in that order - I do a merge somewhere and that somehow messes up the order of the columns). How can I output it to a csv file with the columns in the order that I want? Thanks.
