Hi I am just starting out in R and im trying to upload some data into it. I have saved a small file from excel as a .txt file in the working directory i am using in a folder of the same name as the .txt file. When i write the function to open it I keep getting this message > snow<-read.table("working directory") Error in file(file, "rt") : cannot open the connection

Hi, I need to fit a piecewise linear regression. x = c(6.25,6.25,12.50,12.50,18.75,25.00,25.00,25.00,31.25,31.25,37.50,37.50,50.00,50.00,62.50,62.50,75.00,75.00,75.00,100.00,100.00) y = c(0.328,0.395,0.321,0.239,0.282,0.230,0.273,0.347,0.211,0.210,0.259,0.186,0.301,0.270,0.252,0.247,0.277,0.229,0.225,0.168,0.202) there are two change points. so the fitted curve should look like \ \ /\

Hi Everyone, I want to make 3 lines on the same graph (not as subplots, all in the same window, one on top of each other) and I want them to be quantile-quantile plots (qqplot). Essentially, I am looking for the equivalent of Matlab's "hold on" command to use with qqplot. I know I can use 'points' or 'lines', but these do not give me a qqplot (only appear to work

Hi, Please excuse my ignorance, but I am just learning R (this is my very first day programming in R) and having a really hard time figuring out how to do the following: I have a matrix that is 1000 row by 6 columns (named 'table.combos') and a 1 row by 6 column vector (named 'mine'). I want to find every row in 'table.combos' that equals 'mine' and then count

Hi Again, I am writing a 'for loop' to create a matrix of randomly sampled colors. I've written this loop in matlab and it works fine. I then tried to do it in R and apparently there is something wrong with my syntax b/c every time I run the script, the for loop "blows up" at a different point in the loop. As you can see, I ask R to clear my workspace each time, so there

Hi I am trying to do a logistic regression on a small data file yet when i get up to plotting the first set of graphs instead of 4 I only get one graph, and some error messages. Yet it still looks like the program is doing something due to the "blue wheel" of the mouse. Below is the script copied from R and where I get up to before the message occurs. The data set is based on how

dear Researchers, i am looking for a function to plot a barplot for each mean value and the related standard deviation, and i can close my week. This is an example of my data set. really Thanks in advance for any help or suggestions Gianni My.mean <- data.frame(Mean=c(0.4108926,0.3949009,0.4520346, 0.4091665,0.4664066,0.3048296,0.4297226,0.4056383,

Buen día a todos. Tengo un problema.Podría ayudarme diciendóme cómo se llama la paquetería para encontrar el comando "bs.data", lo he estado buscando para ver como escribir el comando en R y no me aparece una paquetería para ver la descripción. Saludos. [[alternative HTML version deleted]]

Hi, I managed to use the attached data set and figure out the following: flies <- read.table("example12_1.dat",header=TRUE,sep="\t") boxplot(long ~ group, data = flies, horizontal = TRUE, col = "red") I'm very new to R and would like some help with the following: 1. Change the order on the y-axis from 1, 2, 3, 4, 5 to 5, 4, 3, 2, 1.

Dear Sir or Madam: This is an extension to a earlier post, about looping through several thousand files, and testing student's models against a different data-set, called rclnow, for "recall now". The problem is, that the instructor never specified to the students, what they should name their "lm" object. So what they created was: "arbitrary variable name"

Hi, how do I create a string of the comma-separated content of a vector? I've got the vector i with several numeric values as content: >str(i) num 99 and want to create a SQL statement to look like the following where the part '(2, 4, 6, 7)' should be the content of the vector i: select * from [biomass_data$] where site_no in (2, 4, 6, 7) Here my approach (which doesn't

Hi, how can I use rm() on objects named like: paste("site",i,"_data",sep="") while looping through i? I tried rm(paste("site",i,"_data",sep="")) but I get the error that rm() must contain names or text strings which is confusing me as I thought paste() would create something like that...? Thanks, Katharina -- Time flies

Hello, About once or twice a week, dovecot's imap-login process on my system seems gets out of control, eating 100% CPU for about 2 hours. Afterwards everything seems to go back to normal. I am using Dovecot 2.1.7 on a 64 bit Debian wheezy system. When running gdb on the process in this stage, I get the following traceback: #0 0x00007fcba50c5a90 in read () from

Hello, I've set up a tinc "server" named "spitzer" in proxy arp mode, and a client "inspiron" that connects to it. inspiron runs tinc 1.0.16, spitzer runs 1.0.11. Ping and ssh from inspiron to spitzer and other hosts in the network (via spitzer) works fine. Ping and ssh from other hosts in the network to inspiron works fine (i.e. going through spitzer works

Hello, I am investigating a data-loss bug in SSHFS (https://github.com/libfuse/sshfs/issues/72). While the root cause is in SSHFS and has already been fixed, there seems to be some unfortunate interaction with what I believe is an OpenSSH bug: As far as I can tell, when sending a SSH_FXP_OPEN request with SSH_FXF_WRITE (i.e., opening the file write only), and then following up with a

I''m on WinXP SP2, Ruby 1.8.4, Rails 1.1.2. Sometimes when I''m editing a line in script/console - that is, I''m using the cursor keys or backspace key to edit the text on the current line - the cursor suddenly flies off to the previous line out in space somewhere, and typing anything after that just results in characters being entered at weird places. Anybody else

Hi R-ers: I need to compute the distance between 2 street addresses in either km or miles. I do not care if the distance is a "shortest driving route" or if it is "as the crow flies." Does anybody know how to do this? Can it be done in R? I have thousands of addresses, so I think that Mapquest is out of the question! Please rely to: philipsmith at alumni.albany.edu Thank

Hello I have directories named as the names of years eg. 2009 2010 etc. And in this folders eg. 2009 folder there are scanned .tif files like this: 10_09.tif 229_09.tif 3890_09.tif 3890_1_09.tif etc. I would like to samba check correct filenames eg. in folder 2010 there shouldn't be any flies from xxxx_09.tif eg. 229_09.tif only 229_10.tif (_10.tif and vice versa in 2009 there
