**Skip the index column when reading a dataframe** [Data Source](https://www.google.com/url?q=https://s3.amazonaws.com/udacity-hosted-downloads/ud651/wineQualityWhites.csv&sa=D&ust=1537996947820000) When I try to read the data only giving the filename, the first column is only an index list which I don't need. To prevent it from happening, we need to use `col_types` parameter to specify the columns we want to skip. `X1` refers to the first column. Likewise, if you want to skip the 5th column for example, you need to use `X5`. To add more columns to skip, simple add another line of `Xn = col_skip()` separated with a comma within `cols`. ```r library(tidyverse) df.wine <- read_csv("wineQualityWhites.csv", col_types = cols(X1 = col_skip())) colnames(df.wine) ``` The code below gives the same result: ```r df.wine <- read_csv("wineQualityWhites.csv") %>% select(2:13) colnames(df.wine) ``` [Source](https://ugoproto.github.io/ugo_r_doc/Reading_Data_into_R_with_readr/)
