Hello everybody, here is the code I use to read an excel file containing two rows, one of date, the other of prices: library(RODBC) z <- odbcConnectExcel("SPX_HistoricalData.xls") datas <- sqlFetch(z,"Sheet1") close(z) It works pretty well but the only thing is that the datas stop at row 7530 and I don?t know why datas is a data frame that contains 7531 rows with the

Hello everybody, I?ve been looking for a function that would create an excel file in my working directory where I would write my dataframe but I only found the functions to write or read in an existing file that you gave me on my former post or on some websites. I can?t find either functions to manipulate those datas: for example, I would like some lines to be red or green according to their

Hello, the sqlSave function is used in order to write a dataframe on excel. This function creates worksheets using the attribute tablename and writes the data.frame in it. What I want to do is to create this data.frame but being able in case this worksheet already exists to delete the former datas and write the new ones in it. I used the safer and append attributes. When you set safer to false,

Hello, All: The "writeFindFn2xls" function in the "sos" package tries to write an Excel file with 3 sheets ('PackageSum2', 'findFn', 'call'). Unfortunately, it is often unable to do this because of configuration problems that are not easy to fix. I've found 3 contributed packages that provide facilities to write Excel files with

Hola, Pensé que esto iba a ser trivial en R, pero me estoy encontrado muchos con mi problema en internet, y que las soluciones ofrecidas no terminan de funcionar. Estoy intentando leer un fichero .xls en ubuntu con los siguientes paquetes y nada: require(RODBC) conn = odbcConnectExcel("madrid.xls") # open a connection to the Excel file sqlTables(conn)$TABLE_NAME # show all sheets df =

Hola, @javier, me gustaría no tener que hacer nada de forma manual, ni por fuera de r, rstudio. Es decir, el típico comando de linux que me convierta de xls a csv prefiero no usarlo. Me gustaría hacerlo todo desde R. @jorge -> Con RODBC me salta -> Error: could not find function "odbcConnectExcel" Lo que creo que es inevitable en Ubuntu

Hi All, I'm using R 2.11.1 on 64 bit windows XP. The little function I wrote below I use often to import the first 1001 lines in an excel sheet to R. This works fine on the 32 bit version of R but fails on the 64 bit [both on the same machine, using the same function, importing the same .xls file]. The message from 64 bit R is: Error in sqlTables(channel1) : first argument is not an

Dear R users, I've learned today about RODBC package in order to import xls file to dataframes and export the dataframes to xls files. However I have some problems. Please excuse me if these are basic but as I said, I've just begun with this package. Also this email is quite long, but everything is related, so I don't think it would be better to split it. Moreover, there's a

Dear R users, I've already asked this question yesterday, but, though I had answer for the other ones (and they helped a lot, thanks), for some reason didn't get an answer for this one (I would also appreciate to know why, so that I can improve the quality and clarity of my future questions). Here it is again: I'm trying to use RODBC to export dataframes to xls files. When I run

Gracias Jorge por contestar tan rápido. Con gdata hago eso del path, y directamente con el fichero, lo vi en una web, y he intentado todas las opcioens que he visto. En vez de install.packages('rJava', type = 'source') he hecho install.packages('rJava') Ahora probaré, y lo mismo con scan y readLines. He visto en stackoverflow que mi problema puede ser actualizar java,

Muchas gracias Javier por tu respuesta. Si. Para obtener "dataout" se utilizan filas anteriores de acuerdo con la disponibilidad de la variable TOENDREF para cada valor de la variable REF. Por ejemplo, las filas 3 y 4 de "datain" son #REF TIMEREF TOENDREF #3 999 360 150 #4 1099 30 480 En la fila 3, el valor de TOENDREF es 150. Esto indica que hay 150

Hello, I have a date value in excel: 1/4/2010 which in number format gives me 40182. When I read this with read.xls from R I get same 40182 so what I do is that I use the as.Date() function but here is what the as.Date() function returns me: > as.Date(40182) [1] "2080-01-06" Why don't I get the same thing as in excel?
