Hi Sarah
Thank you very much for your pointers.
Is there a way to specify the date string as POSIXct when reading in?
I have tried the following (very inelegant way) and still have no luck.
--- Begin Code ---
# 1st read in the spreadsheet with stringsAsFactors set to FALSE
> abc <- read.csv
Hi bbb_aaa,
The format for the input to the function (gantt.info) is a list. As
Sarah mentions, a data frame is a list, so as long as your columns
have the right names and are in the correct order, it should work. As
you probably know, you can import a CSV file into R as a data frame
using read.csv
Hi,
The help file for gantt.chart states that dates must be in POSIXct
format, and the example shows how to do that. There's no reason that I
can see that you can't use a data frame as input to gantt.chart, but
you need to be very careful that your data frame matches the correct
format. I bet also

Hi
I am trying to generate a complex Gantt chart using the gantt.chart function in
the plotrix package.
Ideally I would like to use a spreadsheet to populate the activities (tasks)
and start and end dates that this function expects and then export the
spreadsheet file as a .CSV text file so I
Wouldn't the obvious problem be that your data file is corrupted or was never
created using saveRDS in the first place? Can you show us a complete example
of creating and attempting to read what was just created?

Hi there,
I faced a weird problem doing a seemingly simple task in R. Specifically,
when trying for reading an RDS file from the working directory, the
following error is appeared.
Code:
records <- readRDS("tweets.rds")
Error:
Error in readRDS("tweets.rds") : error reading from connection

Are you missing values coded as missing values? That is, are they NA? Such
NA-values should be handled by vegan::monoMDS. Naturally, it can be possible
that your data set cannot be meaningfully analysed if you have too many missing
values or missing values are grouped in peculiar ways. Zero-valu
Hi Luca,
How about this?

Hi,
I am a bit rusty with R programming and do not seem to find a solution to
add a number of variables to my existing dataframe. Basically I need to add
n=dim(d1)[1] variables to my d0 dataframe and I would like them to be named
V1, V2, V3, ... , V[dim(d1)[1])
When running the following code:
