I currently work on a draft of an aquatic bioassessment. The conditions tested are the following: ER river water T dechlorinated water control 0.5 + 0.5mg / L of malate T + 1 dechlorinated water control + 1g / L of malate T ED dechlorinated water control SED + ER + river water sediment SED ED + sediment + water dechlorinated. It is the result of AChE in muscle (fillet of fish). The production of

Hi, I have a string "GGGGGGCCCAATCGCAATTCCAATT" What I want to do is to count the percentage of each letter in the string, what string functions can I use to count the number of each letter appearing in the string? For example, the letter "A" appeared 6 times, letter "T" appeared 5 times, how can I use a string function to get the these number? thanks, karena

I am wondering if there is any function in R that is similar to the "scan" function in SAS. I have a data.frame which has two columns as the following: one two 1 2 3 4 5 6 I used the "paste" function to create the third column: three <- paste(one,'-',two,sep="") so the data.frame is like this now: one two three 1 2 1-2 3

I need to create 10 matrices. say matrix 1-10. matrix_1 is 1 by 1 matrix_2 is 2 by 2 matrix_3 is 3 by 3 . . . matrix_10 is 10 by 10 I am just wondering if there are some functions in R that are similar to the macro variables in SAS. so I can create these 10 matrices by doing: for (i in 1: 10) { matrix_$i <- matrix(nrow=i, ncol=i) } rather thank creating these matrices one by one

Following is a function that I wrote (It is working well). It's a simple one, nothing complicated. The only question that I have is a qutation mark issue, I guess. ############################################# funcname <- function(trait.file){ #line1 setwd('/root/subroot') # line 2 load('imge.RData')

I'm trying to sort a DATAFRAME by a column "ID" that contains alphanumeric data. Specifically,"ID" contains integers all preceeded by the character "g" as in: g1, g6, g3, g19, g100, g2, g39 I am using the following code: DATAFRAME=DATAFRAME[order(DATAFRAME1$ID),] and was hoping it would sort the dataframe by ID in the following manner g1, g2, g3, g6, g19,

If a text file has rows of variable lengths. How to read the file into R? I think some people may suggest using 'fill=T', however, it sort of messes the data up, for example, in the text file: a b c d 1 2 3 4 1 8 6 1 2 0 1 1 0 If I read in the file using 'read.table("data", head=T, fill=T), then the data.frame in R will
