Hi, I read in csv files with the following code: res <- vector(mode="list",length=3) for(i in 1: length(res)) res[[i]]<-read.csv(file=paste("/Users/markaltaweel/Desktop/Output/HydroDataOutput",i,".csv",sep=""),header=T,sep=",") This allows me to load the data into an array of length 3, with the res array containing my data from the csv

Hi, I have a scatter plot, with an equation that best fits the scatter plot expressed as: 1/x^.6. I know for normal linear regression lines you can use the abline() command; however, since my best fit line is not linear, how can I draw my line on the scatter plot in a similar fashion to abline(). Thanks for everyone's help again. I appreciate this board's advice. Mark

Hi, I have data stored in a list that I would like to aggregate and perform some basic stats. However, I would like to apply conditional statements so that not all the data are used. Basically, I want to get a specific variable, do some basic functions (such as a mean), but only get the data in each element's data that match the condition. The code I used is below: >

I have a problem where I have two columns of data that I can simply plot using: plot(wV[0:15,3],wY[0:15,3]). This produces my desired plot. Now, say I have a third variable that I would like to introduce and use that variable to set different colors in the plot In this case, say I wanted values greater than 0 to be "blue" and values less than 0 to be "red" Basically, my

Hi, I am trying to perform various functions on a list with a number of elements. For example. I would like to take the mean of different variable values in the entire list. As an example, say I have a list with 1000 elements and variables called Id and Tick. What I would like to do is take the mean of a variable called X for each Tick in the data element. So, there can be say 1 to 600 tick

Hi, I am trying to load csv type data from a folder. However, rather than syntax that simply loads one file at a time I was wondering if there is a method that loads all data from a specific folder. For instance, I have the following data files in a folder nebraskaStats: 10-1-2009_10-7-2009.txt 10-2-2009_10-8-2009.txt 10-3-2009_10-9-2009.txt ....etc. (245 total files in folder) Each file

Hi, I had another question. If you had say a vector (e.g., called data) with 235 elements and each element looked like the following data[[1]] Column A-B Column Z-S Column A-S.... 1 2 5 ....... data[[2]] Column Z-B Column A-S Column A-B.... 2 1 3 ....... Anyway, each element consists of one row

Hi, I am trying to do a kruskal wallis test on two lists, fVisited and cSN: fVisited[[1]] [1] 0.17097623 0.30376141 0.17577266 0.14951855 0.03959753 0.08096217 0.05744888 0.02196257.... .... cSN[[1]] [1] 0.08557303 0.36477791 0.19601252 0.12981040 0.05351320 0.10385542 0.03539577 0.03106175.... So if I just want to do a test on just one of the entries this is simple enough:

Hi, I am trying to sum column information in a list with 3 instances. For example: ID Traversed ID Traversed ID Traversed 1 5 1 7 1 8 2 8 2 11 2 7 3 11 3 22 3 16 What I want to do is sum the

Hi, I have a vector and a list, with data I would like to multiply together. So for instance I have a vector s: [[1]] [1] 44308 [[2]] [1] 4371 Also, I have a list d: [[1]] [1] 1201 6170 2036 2927 1625 1391 2074 1453 3172 3027 4691 3719 1185 320 2071 1027 1046 1186 1403 580 1382 440 8 174 [[2]] [1] 6521 688 2678 3409 3033 1608 3618 1461 1836 2104 879 1095 2630 1591 2986 703 2548

Hello, we've had some serious trouble with a two-node Xen-based OCFS2 cluster. In brief: we had two incidents where one node detects an idle timeout and shuts the other node down which causes the other node and the Dom0 to hang. Both times this could only be resolved by rebooting the whole machine using the built-in IPMI card. All machines (including the other DomUs) run Centos 5.2

Hai, If not, well, very stange, i have about 7 Jessie's here with samba and i dont have any problems. I think systemd is blocking your startup of samba due to multple errors on startups previously.

Dear all, Good day! I have a problem in reading Excel files in R and appending them to each other. Suppose we have several Excel files in a directory with headers and want to use R to append them in a single file with an additional variable in the final file indicating from which files the data come from. As I have many Excel files and their sizes are very big I should write a loop in R to do

Hi, I am trying to simultaneously remove duplicate variables from two or more variables in a small R data.frame. I am trying to reproduce the SAS statements from a Proc Sort with Nodupkey for those familiar with SAS. Here's my example data : test <- read.csv("test.csv", sep=",", as.is=TRUE) > test date var1 var2 num1 num2 1 28/01/11 a 1 213 71 2

Dear all, I am trying to include confidence intervals in a xyplot. This is what I am doing: xyplot(x ~ y|z, alpha = 1,band = "global",panel = panel.locfit) (more specifically, in my case x is a binary response from a logistic regression model) The output plot was fine but it did not include the confidence intervals Anyone knows how to do it? (xYplot did not work either) many thanks
