similar to: Write a blank line to CSV

Greetings, I have a vector of values that are a word followed by a number, e.g., x = c("Apple12","HP42","Dell91"). The goal is to split this vector into two vectors such that the first vector contains just the words and the second contains just the numbers. I cannot use strsplit (or at least I do not know how) as there is no obvious separator. I can use sub to

Hello, A quick question for my edification. When I run the following (R 2.8.1 on Microsoft Windows): > d = data.frame(x1=c(1,2),x2=c(3,4),y1=c(5,6),y2=c(7,8)) > reshape(d,varying=c("y1","x1","y2","x2"),v.names=c("y","x"),dir="long") I found myself surprised by the results--the column labeled "y" is actually

Hi, How can I write the output to an excel (csv) file without printing row names (i.e without breaks). Here is my code: library( fn <- function() { q <- c(1,2,3) write.csv(q,"C:/Temp/op.xls", append = TRUE, row.names = FALSE,quote = FALSE) } # Function Call for(i in 1:3) { fn() } Present Output : x 1 2 3 x 1 2

Greetings, I have a vector of the form: [10,8,1,3,0,8,NA,NA,NA,NA,2,1,6,NA,NA,NA,0,5,1,9...] That is, a combination of sequences of non-missing values and missing values, with each sequence possibly of a different length. I'd like to create another vector which will help me pick out the sequences of non-missing values. For the example above, this would be:

Hi, I am confronted with this error while trying to read csv file into R session. Though it is warning message, I noticed that the whole file was not read properly. After having gone through the whole file, unable to identify error in file. I am copying the last 2 rows in original csv file after which the reading was not proper. (cannot enclose file because of big size) TRANSCONTINENTAL GAS -

Dear R users, I have recently begun to reuse some functions I made several months ago. The scripts write to a .csv file using the 'write.csv' function with the append option set to TRUE. This used to work fine, albeit with the warning "appending column names to file". I upgraded to R version 2.11.0 on OSX 10.5.8 and 'write.csv' will no longer append any files - I get the

Hello, I'm attempting to create a data frame with correlations between every pair of variables in a data frame, so that I can then sort by the value of the correlation coefficient and see which pairs of variables are most strongly correlated. The sm2vec function in the corpcor library works very nicely as shown here: library(Hmisc) library(corpcor) # Create example data x1 = runif(50) x2 =

I'm running R 2.11.0 on a 32-bit Windows XP machine. Whenever I try to write a csv file with 'append' set to TRUE, I get this message: attempt to set 'append' ignored. Obviously, this is no good, since R is deleting my previously saved data files, rather than appending to them. What can I do to fix this? -- View this message in context:

I've always been frustrated that R never puts a label on the column name for a column of row names. This is usually the "key" in a database table, and it sure would be nice to carry a "key" name along with the data instead of the field being blank. So, why is it a good idea for it to be blank? ?write.csv says this: CSV files By default there is no column

Is there a way to make any of the write functions (.table or .csv) append to the same file? I get this warning message and do not know how to enable the appending. Warning messages: 1: In write.csv(names(Lbys)[c], fo, append = TRUE) : attempt to set 'append' ignored 2: In write.csv(Lbys[[c]], fo, append = TRUE) : attempt to set 'append' ignored Regards, Alex van der Spek

Hi, Use `check.names=FALSE` head(dd,2) #? Phylo.Tree Genesis.Tree #1????????? 1??????????? 2 #2????????? 2??????????? 3 ?dd <- data.frame("Phylo Tree"= c(1:10), "Genesis Tree"= c(2:11),check.names=FALSE) head(dd,2) #?

Hello, This is a question motivated by curiosity, not a pressing problem. Any responses are much appreciated! In the following code, function reg1 calls glm with a formula object while reg2 uses a string. In both cases, glm works; however, in the second case, the add1 function fails with the following message: "Error in eval(predvars, data, env) : invalid 'envir' argument."

Dear Friends. Greetings! I have asked the question of how to set up a blank file and write a list to it as a row for many times, with the number of lists unknown. I have received many beautiful solutions. Thanks go to Professor *Murdoch, Professor *Menne, Professor Grothendieck and Dr. Olshansky.

i have a loop which looks likes this: > data.info <- rbind(data.info, cbind(station.id, year, date, > max.discharge)) + y <- split(data.info, data.info[station.id]) + for (i in names(y)) {write.csv(y[[i]], file=paste(i, ".csv", sep=","))} i am wondering, where the file (which i am about to write in .csv format) will be saved? i looked at ?write.csv and

I am looping over a data set and at each loop I am creating a dataframe ?mydata? That I wanted to be saves in a .csv file, but I want all the results to be saved in the same file and this is the way I do it write.csv(mydata, file= ?data.csv?=F, append=T) . the csv file looks fine but I always get the following warning message Warning messages: 1: In write.table(mydata, file =?data.csv?, ... :

I would like to export a dataframe to a .csv using: >write.csv(dataframe,"dataframe.csv") but I need to add four "header" lines to the csv that are not part of the dataframe (which itself has a line of column headers). The difficulty (for me, at least!) lies in the requirement that certain elements of the header (X, Y and the number of "Q"s - please see example

Hi, I am writing a function that writes to a csv file for every call. However, for the subsequent calls, I want to append the data to the existing csv file without appending the column names again.
