Dear Sir / Madam, I am new for R coding. Kindly help me out in sorting out the following problem. There are 50 rows with six coloumns(you could see in the attached .txt file). I wish to go for filtering this 50 rows for any one of the six coloumns satisfying the value >= 64. I need to have a final table with rows having >= 64 value in any one of the six coloumns and the rest could be

Hello, I am facing a problem in drawing heat map using R. I have a 70X3 matrix and I want to draw a heat map with 1 coloumn on X axis another on Y axis and want to show the value of 3rd coloumn using heat colours. Could you please help me with this . Thank you . Regards, Sumit [[alternative HTML version deleted]]

Hi, I'm writing for a little help. I have a dataframe with same NA value and I'd like to obtain the means of the value of a coloumn grouped by the levels of a factor coloumn of the datframe. I'm using the function "tapply" but I see that if only a NA value is present the result is NA. There is an option to have the correct result or I must use an other function? Thanks of

problem in starting xend I tried to install xen, but got some errors when starting xend. as I logged in and tried to start xend (/etc/init.d/xend start). I just got six-seven dot (.) printed out, then it stops. I looked more closely and found that xend could not start. then I looked at /var/log/xend-debug.log. here is the last few lines: ^^^    Exception starting Xend: no element found:

Hi, I need your help!! I imported a big coloumn vector from a txt file but it results as mode :"list" I want to change it in numeric otherwise I can't do my analysis. This is what i get: mode (data) <- "double" Error in eval(expr, envir, enclos) : (list) object cannot be coerced to type 'double' > Thanks a lot!!! Alessandra -- View this message in

Dear all, I have been trying to understand what runif() is telling me. I am generating lots of numbers (billions and billions (wow, I''ve dreamed about saying that for many years... :-) ), for a distribution that has the following quantile function: 1 / (2 * sqrt(1 - p)) (that is, the distribution has a lower cutoff) As you can imagine, this has rather heavy upper tail. I was

Hi, I'd like plot a bar graphic of a array. I'd like to have the values of the single columns as juxtaposed bars (like in "barplot" with beside=TRUE) and I'd like to have the values of the single columns expressed like percentage of the sum of the coloumn. In this way all the bars are composed by the sum of the percentage of the values of a coloumn (with different colors)

  Hello list, i have a very simple question about matrix assignment. i did like this. res<-1:30 dim(res)<-c(5,6) ind<-1:6 now i want to assign the value of this variable ind to first coloumn in matrix res. like res[,1]<-ind but this code is giving error , Actualy i have a for loop and value of ind variable is changing every time ,,total 6 times,,i want to assign every vlaue

To my knowledge, this has not been reported previously, and doesn't seem to have been changed in R-devel or R-patched. If M is a matrix with coloumn names, and mod <- prcomp(M) # or princomp then predicting a single observation (row) with predict() gives the error Error in scale.default(newdata, object$center, object$scale) : length of 'center' must equal the number of

I am having a similar problem understanding the data structure of the "yarn" dataset described in the "[R] data structure for plsr" posts. I have spectroscopic data I'd like to run through a PLSR and have read the tutorial series, but still do not understand the data format required for the code to process my data. My current data structure consists of a .csv file read into

Dear all, There has been some time since I asked about interpolation in higher (>2) dimensions, and I must admit I failed to write a function to do this myself the last time, but eventually ended up doing it in MATLAB. I tried to translate the MATLAB code, but MATLAB code is so much more opaque than R (S) code, so I failed that too, mainly because I could only get one MATLAB session, I would

Hi all, I am getting problem with "read.csv()" command the problem is I have one file which is saved in "ANSI" while I am trying to open with R-Project its opend and all the cloumn names are comming proper like for the command names(kk) "FILEID" "UNIQUEID" "LATESTFLG" "ACTIVEFLG" "PROJROLEID"

What I would like to do is have two identical * servers which accept registrations of sip extensions 4000-4999. If I define a rrDNS or LinuxHA then I should have load-balanced registrations. However, say ext. 4001 is registered on *1 and 4002 is registered on *2, if 4001 tries to call 4002 then I would like to do something like: - lookup 4002 on *1, try to establish a call if it's

Dear users, please help to define the following data structure: I would like to have a matrix, where every element is a container of different size , containing real numbers. The containers (bins) are addressed by an index pair [i,j] (i is number of corresponding row of the matrix, j is the coloumn of the matrix). The containers are initially empty, I would like to fill them

Hello, I find strange number in my merge data set. My first coloumn consist row numbers. ----------------------------------------------------------- my.data: AbsTime RelTime PE_ID Event Delay 4238 1208514343.812086 107.153637 4 EKA 51620 ################################## Host.data: ID Host 4 4

Hi, Thanks for your response, it nearly worked! But it only wrote one coloumn of data and not the three columns I need. Using fixef(m1) doesnt give the same results as coef(m1) when you are using more than one random effect. I need the coefficients for each individual so I use coef(m1) to get this which results in an object of class lmer.coef, 3 columns by 700 rows. as.data.frame() wont work on

Hi dear all, i have a data (data.frame) which contain y and x coloumn(i.e. y x 1 0.58545723 0.15113102 2 0.02769361 -0.02172165 3 1.00927527 -1.80072610 4 0.56504053 -1.12236685 5 0.58332337 -1.24263981 6 -1.70257274 0.46238255 7 -0.88501561 0.89484429 8 1.14466282 0.34193875 9 0.58827457 0.15923694 10 -0.79532232 -1.44193770 ) i changed

Hi all, I am wondering in R, suppose I did the principal component analysis on training data set and obtain the rotation matrix, via: > pca=prcomp(training_data, center=TRUE, scale=FALSE, retx=TRUE); Then I want to rotate the test data set using the > d1=scale(test_data, center=TRUE, scale=FALSE) %*% pca$rotation; > d2=predict(pca, test_data, center=TRUE, scale=FALSE); these two
