Dear R users,   Does somebody know the way to import many files by a single command in R ? I have 50 files in a directory and now, i am importing the files repeatedly (one by one). If there is a way to import all files at a time, it makes much more easy and save times too. Thanks in advance.     Sincerely, Ram Kumar Basent Wageningen University, the Netherlands   [[alternative HTML

Dear R users,   It may be very simple but it is being difficult for me. I have two vectors with some common string. And, i want to combine into a vector in such a way that it includes string from both vectors and make a unique.   For example:   x <- paste(rep("A",5),1:5,sep = ".") x [1] "A.1" "A.2" "A.3" "A.4" "A.5" y <-

Hi R users, I want to calculate the partial correlation (first or second order) and their corresponding significance test (p-value). I used > library(corpcor) and "cor2pcor" function to calculate partial correlation but could not calculate "p-value". If some one knows the R package or function to calculate corresponding "p-value", It will be great help. Thanks  

Dear all,   I did ANOVA for many response variables (Var1, Var2, ....Var75000), and i got the result of p-value like below. Now, I want to select those predictors, which have pvalue less than or equal to 0.05 for each response variable. For example, X1, X2, X3, X4, X5 and X6 in case of Var1, and similarly, X1, X2.......X5 in case of Var2, only X1 in case of Var3 and none of the predictors in case

Dear R users,   I am new user for elastic net. I am trying to use elasticnet library. I have marker data with 359 markers and 168 samples, and response is metabolites. I am trying to do regression between a metabolite and markers.  But i am getting the following error:   > en<-enet(marker,as.numeric(vio),lambda=0.5,normalize=FALSE,intercept=TRUE) Error in one %*% x : requires numeric

Dear R users, I am not good in R-language programming. So, i need your help. I want to convert my lower-triangle value of symmetry matrix into a vector with their row and column name. I found a function called "sm2vec" in "corpcor" package but it give only a vector of values but not row and column names. But i also want ROW and COLUMN name together with their corresponding

Hi everybody,   I am doing principal component analysis (PCA) using "prcomp' function. When i did "Biplot", i did not found interesting result and it is based on Principal component (PC) 1 vs PC2. Now, i want to see"Biplot" in combination of either PC1 vs PC3 or PC2 vs PC 3. I did not get the ideas. Does any one have ideas ? I am optimistic on getting some idea.

Hi! I am new to R just 3 days in it and i apologize if my questions seem very trivial and consumed your valuable time. I am coding in perl and i stumbled upon R regarding plotting good statistical graphs. I tried the kmean clustering for a large matrix ,say > 150 * 150 . I tried the example code given in the tutorial to perform 2d plot # i ranges from 2 to 10 cl <- kmeans(x, i, 20)

Dear all,   Does some body have idea on how to extract Type III sum of Square from "lm" or "aov" function in R ?

Hi list, I've thus far not found a solution to my problem and hope someone can help. I have a data matrix and wish to plot a stacked bar plot using barplot(). This is simple enough, but I have a problem with the legend labels being in the reverse order from what I want. The default appears to have labels ascending bottom-to-top reflecting bottom-to-top sub-bars, but I would like the

Hello all, When using the 'barplot' function, how would one go about creating labels on the top of the bars corresponding to the actual frequency values (i.e., the height of the bar). For histograms, one can use the 'LABEL=T' parameter to this effect, but it is not available for barplot. Must one manually create such labels for a barplot (perhaps using mtext)? Thanks.

HI, Dear R-community: I have the following codes to plot the conditional histogram, is a way to label the bars by the percentage values in the conditional histogram? h<- sample(1:14, 319, rep=T) c<- sample(1:14, 608, rep=T) n<- sample(1:14, 1140, rep=T) vt<-c(h, c, n) ta<-rep(c("h", "c", "n"), c(319, 608, 1140)) to<-data.frame(vt,ta)

Greetings ... I hate to ask these questions, but I dought I will get a straight answer from an Salesmen ...

Hello, I try to make barplots with rather wide labels. A simplified example of this: x <- c(12, 33, 56, 67, 15, 66) names(x) <- c('Richard with a long surname','Minnie with a long name,'Albert','Helen','Joe','Kingston') barplot(x, las = 2) Now the label 'Richard with a long surname' is too long to fit beneath the bars. A simple solution

Hi, I have been trying to get the label under the total column - i.e. a mean value of columns 2 to 6 - in a barplot I generate with this script: t1 <- tapply(A, B, sum) t1[8] <- mean(t1[2:6]) t1 <- as.table(t1) barplot(t1, ylim=c(0,3000)) mtext("Var1", side = 1, line = 3) mtext("Var2", side = 2, line = 3) I have been trying to use axis(1, at=1:8,
