I am attempting to emulate the VLOOKUP function from Excel in R. I want to compare one column (coll.minus.release) with another (release.days) to get the number of parasitoid released at that time (TotalParasitoids). for example: coll.minus.release release.days ParasitoidTotal -12 -266 1700 8 -259 1000 8

I have two files with dates and prices in each. The number of rows in each of them will differ. How do I create a new file which contains data from both these files? Cbind and merge are not helpful. For cbind because the rows are not the same replication occurs. Also if I have similar data how do I write a vlookup kind of function? I am giving an example below: Say Price1 file contains the

Hi I''m looking for an Excel Vlookup type function in R. Example: list <- c(1,2,3,4,5,6,7) base <- c(2.2,3,5.2) What I want is, for each number in base, the highest value in list, which is equal to or less than the number in base So the results would be: base ? ? ? ? list 2.2 ?------> 2 3 ? ?------> 3 5.2 ?------> ?5 Thanks for your help!

Hi R-users,   I would like to search for the values of seq that match my rand values.  In excel I will use =VLOOKUP(G2,$E$2:$F$32,2).  For example, for rand=.262 it will give me approximately seq=120 and rand=0.964293344, seq=460 and etc.   E           F     G cdf         seq   rand 0.00E+00    0     0.262123478 1.56E-03    20    0.964293344 1.55E-02    40    0.494827113 5.30E-02    60

Hi,   Does R has something similar  to vlookup function in excel?   Thank you for the info. [[alternative HTML version deleted]]

Hi, A quick beginner's question. I have two time series, A with daily data, and another B with data at varying frequencies, but mostly annual. Both the series are sorted ascending. I need to merge these two series together in the following way: For any entry of A, the lookup should match with B until we find an entry of B that's larger than A's. For all A[i], i = 1,...,N and B[j],

Hello! Hope there is a nifty way to speed up my code by avoiding loops. My task is simple - analogous to the vlookup formula in Excel. Here is how I programmed it: # My example data frame: set.seed(1245) my.df<-data.frame(names=rep(letters[1:3],3),value=round(rnorm(9,mean=20,sd=5),0)) my.df<-my.df[order(my.df$names),] my.df$names<-as.character(my.df$names) (my.df) # My example lookup

Hello, I have a matrix and I want to sample 20 rows that are the the percentiles of 0-100 in 0.05 increments. I have a vector of my sequence (0, 0.05, 0.10, 0.15,....1.0) and also a normalised vector of rownumbers. That is, there are 234 rows (for example) so I do perc<-c(1:234/234) which looks like a bunch of numbers from 0 - 1. In Excel (which I try not to use at every possible

Hello I have been struggling with this simple looking problem. I have two dataframes. The first one contains ID, date, and revenue information for specific suppliers. id lastdate depvar A 5/10/2017 10 B 8/16/2017 20 C 2/14/2017 30 D 9/5/2017 40 E 8/1/2017 50 F 11/4/2017 60 G 6/22/2017 70 The second dataframe contains timeseries data of each supplier in different columns. For example Column A are

I have a lot of java data analysis code I have written for processing 400MB per day of compressed packet sniffer data. I have been playing with R recently and struggling to understand where the dividing line between languages like java and R is in terms of which sorts of code in makes sense to write in each. It struck me the other day, as I was using excel to manually manipulate large tables of

Dear useRs, I am sure this is a fairly simple problem, but I just cannot get my head around it. I have a dataframe which contains several factor variables. I can use table() to tell me how many different combinations there are of these variables. What I should like to do is to add a column to my original dataframe which labels each row according to the unique combination of factors. E.g. in

Greetings, I have a CSV file with three fields. eg. a1,b1,c1 a2,b2,c2 .... I wanted the output to be: b1,c1,a1 b2,c2,a2 .... the command cut -d, -f2,3,1 <file> returns a1,b1,c1 cut -d, -f2,3 <file> works as advertised. Is it specific to linux? In that case how do I go about swapping two columns? I do not think a gazzillion byte gui is required. The file size is about 43Megs.
