Hi, all I would like to use R to perform k-means clustering on my data which included 33 samples measured with ~1000 variables. I have already used kmeans package for this analysis, and showed that there are 4 clusters in my data. However, it's really difficult to plot this cluster in 2-D format since the "huge" number of variables. One possible way is to project the

HI,All I am trying to create a heatmap with 24 samples with 15672 varibles, I read in the table in R, and then made it as a matrix, then try to create the heatmap using heatmap(x,...) However, I received the error message as: > heatmap(t(x)) Error: cannot allocate vector of size 936.8 Mb R(2925,0xa0b16500) malloc: *** mmap(size=982261760) failed (error code=12) *** error: can't allocate

Hi all: I have a question about lm on t-test. data(sleep) I wanna perform t-test to test the difference between the 2 groups: I can use: t.test(extra~group) The t.test result shows that:t = -1.8608; mean1=0.75,mean2=2.33 But I still wanna use: summary(lm(extra~group)) Intercept=0.75,which is mean1,just the same as t.test. group2=1.58 means the difference of the 2 groups,so

Dear R users, I am a beginner in R trying to apply the thin plate spline method to my climate data. I used the example in R to do so, and the lines seem to run fine ( I am not getting errors) but I am not getting any output in the form of graph or anything. I got a warning message saying that 'surface extends beyond box'. Any help is much appreciated. thanks minti

Hi all, I'm writing a function that summarizes objects, however, when a Date variable is present in the objects it doesn't work. How can I handle with this problem? D

If there are many character variables,and I want to get the mosaic plot of every pair of each variable,how to do then? If the variables are numeric, I can use pairs to get paired scatter plot. But as to the character variables, how to get the "paired mosaic plot"? Many thanks. -- QQ: 1733768559 At 2015-02-07 17:04:26,"Jim Lemon" <drjimlemon at gmail.com>

Hi, I have a question about the memory layout of the Xen hypervisor, dom0 and domU. *The goal I want to achieve is: I want to show which RAM area is used by hypervisor, which RAM area is used by dom0, which RAM area is used by each domU (PV guest domain). I hope to know the above information when xen is booted as well as when xen is running some domUs. I already know that we can dedicate a fix

Each virtio scsi HBA has global request queue limits. But the passthrough LUNs (scsi-generic) come from different host HBAs may have different request queue limits. If the guest sends commands that exceed the host limits, the commands will be rejected by host HAB. To address this issue, this patch adds a per-LUN parameter query via the control queue, and defines some parameter query types. The

Hi, I am wirting a R script to process some data routinely and have a problem when try to get the content of object in ls()? Here is the script: > ls() [1] "a" "b" [3] "files.num" "fll92_1a_gpr" [5] "fll92_1a_gpr_norm" "fll92_1a.gpr.norm.scale" [7] "fname" "fullnames" [9] "gal" "galfile" [11]

As to the function"pnorm",the default degree of freedom(df) is infinite. I wanna know how to set the df as I want. Help on pnorm doesn't have df setting.The only choice are:"mean, sd, lower.tail, log.p",but no df. For instance: sample size=6 df=6-1=5 t value=9.143 I wanna to the corresponding p value by using function "pnorm". How can I do it? Thanks a lot

Hello sir: There are 2 questions about string. 1 How to calculate the width of a string? e.g string "abc"'s width is 3; 2 How can I get the "substring" in such kind of condition: "f:\\JPCS_signal.txt" "f:\\PC1_signal.txt" "f:\\PC2_signal.txt" What I wanna get is "JPCS" "PC1" "PC2".How can I achieve them by R

Dear all, Very simple question, but apparently uneasy to solve in R: I have a sampling of a variable x: (3, 4. 5, 2, ...) I want to know: - the mean <x> -> mean(x) - the uncertainty on <x> -> std.error(x) ? Or sd(x)? - the standard deviation of x -> ? - the uncertainty on the standard deviation -> ? Anyone has an idea? Thanks in advance,
