Weird error in R when importing (64-bit) integer with many digits

由 这一生的挚爱 提交于 2019-11-26 17:13:51
问题 I am importing a csv that has a single column which contains very long integers (for example: 2121020101132507598) a<-read.csv('temp.csv',as.is=T) When I import these integers as strings they come through correctly, but when imported as integers the last few digits are changed. I have no idea what is going on... 1 "4031320121153001444" 4031320121153001472 2 "4113020071082679601" 4113020071082679808 3 "4073020091116779570" 4073020091116779520 4 "2081720101128577687" 2081720101128577792 5

I am trying to import a csv that is in Japanese. This code: url <- 'http://www.mof.go.jp/international_policy/reference/itn_transactions_in_securities/week.csv' x <- read.csv(url, header=FALSE, stringsAsFactors=FALSE) returns the following error: Error in type.convert(data[[i]], as.is = as.is[i], dec = dec, na.strings = character(0L)) : invalid multibyte string at '<91>ΊO<8b>y<82>ёΓ<e0><8f>،<94><94><84><94><83><8c>_<96>񓙂̏󋵁@(<8f>T<8e><9f><81>E<8e>w<92><e8><95>񍐋@<8a>փx<81>[<83>X<81>j' I tried changing the encoding ( Encoding(url) <- 'UTF-8' and also to latin1) and tried removing the read.csv

Imported a csv-dataset to R but the values becomes factors

由 痞子三分冷 提交于 2019-11-26 09:29:05
问题 I am very new to R and I am having trouble accessing a dataset I\'ve imported. I\'m using RStudio and used the Import Dataset function when importing my csv-file and pasted the line from the console-window to the source-window. The code looks as follows: setwd(\"c:/kalle/R\") stuckey <- read.csv(\"C:/kalle/R/stuckey.csv\") point <- stuckey$PTS time <- stuckey$MP However, the data isn\'t integer or numeric as I am used to but factors so when I try to plot the variables I only get histograms,

Why am I getting X. in my column names when reading a data frame?

问题 I asked a question about this a few months back, and I thought the answer had solved my problem, but I ran into the problem again and the solution didn\'t work for me. I\'m importing a CSV: orders <- read.csv(\"<file_location>\", sep=\",\", header=T, check.names = FALSE) Here\'s the structure of the dataframe: str(orders) \'data.frame\': 3331575 obs. of 2 variables: $ OrderID : num -2034590217 -2034590216 -2031892773 -2031892767 -2021008573 ... $ OrderDate: Factor w/ 402 levels \"2010-10-01\"

How to read only lines that fulfil a condition from a csv into R?

由 六月ゝ 毕业季﹏ 提交于 2019-11-26 07:34:05
问题 This question was migrated from Cross Validated because it can be answered on Stack Overflow. Migrated 5 years ago . I am trying to read a large csv file into R. I only want to read and work with some of the rows that fulfil a particular condition (e.g. Variable2 >= 3 ). This is a much smaller dataset. I want to read these lines directly into a dataframe, rather than load the whole dataset into a dataframe and then select according to the condition, since the whole dataset does not easily fit

How to detect the right encoding for read.csv?

由 孤街浪徒 提交于 2019-11-26 07:01:08
问题 I have this file (http://b7hq6v.alterupload.com/en/) that I want to read in R with read.csv . But I am not able to detect the correct encoding. It seems to be a kind of UTF-8. I am using R 2.12.1 on an WindowsXP Machine. Any Help? 回答1: First of all based on more general question on StackOverflow it is not possible to detect encoding of file in 100% certainty. I've struggle this many times and come to non-automatic solution: Use iconvlist to get all possible encodings: codepages <- setNames

read.csv, header on first line, skip second line [duplicate]

问题 This question already has an answer here: How can I read the header but also skip lines - read.table()? 5 answers I have a CSV file with two header rows, the first row I want to be the header, but the second row I want to discard. If I do the following command: data <- read.csv(\"HK Stocks bbg.csv\", header = T, stringsAsFactors = FALSE) The first row becomes the header and the second row of the file becomes the first row of my data frame: Xaaaaaaaaa X X.1 Xbbbbbbbbbb X.2 X.3 1 Date PX_LAST

Specifying colClasses in the read.csv

由 我是研究僧i 提交于 2019-11-26 06:17:08
问题 I am trying to specify the colClasses options in the read.csv function in R. In my data, the first column \"time\" is basically a character vector while the rest of the columns are numeric. data <- read.csv(\"test.csv\", comment.char=\"\" , colClasses=c(time=\"character\", \"numeric\"), strip.white=FALSE) In the above command, I would want R to read in the \"time\" column as \"character\" and the rest as numeric. Although, the \"data\" variable did have the correct result after the command
